Question 1
2 out of 3 points
Daphne has been a member of a research team studying interpersonal aggression among
preschoolers for more than a year. In that time, her team has repeatedly employed a
consistent set of techniques and procedures to study preschoolers as they interact in a
number of settings. The procedures revolve around volunteer mothers bringing their
children to the university child development lab for a “play session” that is the basis of
the formal observations. Settings they have studied so far include: the university preschool, affluent local day-care centers, and a pre-kindergarten program being offered in
the neighborhood school district. All of these settings were fairly racially homogenous.
Daphne has just learned that a friend of a friend can help her gain research access, in the
near future, to preschoolers in an unusually racially diverse though impoverished
preschool setting. Daphne decides she has no time to prepare a formal research proposal
before embarking on the study. “Besides,” she thinks, “this study should go just like all
the others we’ve done.”
Is Daphne leaving herself open to problems in this situation, or is she safe moving ahead
with no formal proposal, given how familiar she is with the study techniques and
procedures?
Answer
Selected
Answer:
Correct
Answer:
It depends, Daphne is in a tight situation. She has to use her time to best of
her ability to use survey and questionaires for the volouteer mothers so that
she can get enough data and resources to help her get a start on her
proposal.
Daphne is setting herself up for potential problems by skipping the formal
proposal. Without the exercise of writing the proposal, Daphne may not
stop and carefully think through all the ways in which this study may not be
like previous studies. For instance, Daphne needs to consider whether the
mothers of the children in this more impoverished setting will be willing or
available to bring their children to the lab sessions. She also needs to
consider whether the techniques being used to record peer interactions are
adequate, given that this sample is more racially heterogeneous than
previous samples. There may be additional or different questions that
should be added to the study to capture the richness of the new situation. It
may turn out that the present design will translate fairly seamlessly to the
new setting. But without the detailed planning that the well-written proposal
forces the researcher to undertake, it is entirely possible that Daphne will
encounter a dearth of research participants and data that do not capture the
richness of the interactions among the participants that do volunteer.

In historical research involves getting data sources whether it is primary or
secondary. collecting historical meyhods, online databases for historical
events, evaluating and interpreting historical data, external evidence,
internal evidence, searching for roots, psychological or conceptual historical
research.

Answer:
In addition to gathering and organizing data, the researcher must
interpret those data if the resulting report is going to be a historical
research study rather than a historical narrative. It is in the
interpretation that the string of events takes on meaning. Students may

Question 6
3 out of 3 points
Why is it important that the researcher articulate, as clearly as possible, all assumptions
that affect the research problem?
Answer
Selected
Answer:
Correct
Answer:
It is important for the researcher to articulate, as clearly as possible, all
assumptions that affect the research problem because whereas a hypothesis
involves a prediction that may or may not be supported by the data, an
assumption is a condition that is taken for granted, without which the
research project would be pointless. In research, assumptions are self
evident truths that any reasonable person might accept.
There are at least two reasons to articulate assumptions underlying a research
problem. First, these assumptions will guide the selection of research questions
and/or the formation of hypotheses, as well as the interpretation of the
data. Clearly stating the assumptions assists the reader in evaluating the merits
of the study and the conclusions drawn from it. Second, to the extent that the
researcher is aware of his/her assumptions, these can be incorporated into the
study design as needed to promote the validity of the conclusions drawn from
the study.

Answer
The Information Revolution is transforming society - creating new careers,
Selected
new industries, new academic disciplines and the need for new programs of
Answer:
education and research. Being an informed citizen in this Information Age
requires knowledge of computing systems, global communications networks,
and interactive information resources. The requisite level of knowledge goes
beyond being comfortable with computing tools. It requires the ability to
design, to writing, to experimentation, to artistic expression, and to problem
solving. In the Information Age, our ideas are no longer constrained solely by
what is physically possible, but by what is computationally realizable
However, we see several significant disadvantages with this model. First, we
believe that the scale of interactions that are required would be unwieldy for
any single department to manage - both in terms of the sheer number of faculty
and the intellectual breadth. We envision research connections and new
educational programs integrating computing with the arts, the humanities, the
social sciences, engineering, the physical sciences, the life sciences, and the
professional schools. The number of faculty involved and their disparate
backgrounds call for focal areas, such as the three we identified above, that in
and of themselves could be as large as many departments. The combination of
these focal areas with core computing and information science could be the
size of a small college, and far broader intellectually.
A second critical problem that we see with the department model is the
necessity of maintaining the strength, identity, reputation, and visibility of core
activities such as the Computer Science Department and the computer
engineering area. Adding a broad range of people to the departments that
contain these core activities could easily be perceived as diluting their strength
with "soft" or "applications" work. Thus we do not see the common home for
broader activities fitting inside any single department. We have also seen,
during campus discussions, that the model of diluting a department with a large
number of joint appointments is damaging to the fundamental nature and
purpose of departments.

Question 9
2 out of 3 points
Sometimes students believe that taking the time to prepare a complete and carefully
designed research proposal is something to be preached, but not really practiced. Identify
at least two different problems related to research design that are commonly encountered
when doing research. For each problem, explain how a complete and detailed research
proposal would help the researcher avoid the problem.
Answer
Selected
Answer:
Manipulation of data
Every researcher tries or does one or the other kinds of manipulation of
data. May bemultiplying the sample size or to make the result in
the way they want. The lack of confidence over the result they may
get after the completion of study is the reason for manipulation of result.
This never reveals the reality, as the intuition of the researcher is
guided by mere theoretical knowledge. In reality sometimes
theory and practicemay be contradictory. Some researchers just
finish off their study by simply sitting intheir home; they don’T t even
interact with their subject or have any one.
Lack of availability or access to literature needed.
This is a major problem faced during the literature review. The lack of
availability of access to Internet, ignorance of the way to search
needed articles from journals andother databases are other
problems. Searching books and newspaper articles

Common problems may include the following:
• Variables of interest are not well or fully represented by the chosen
measurement instruments.
• Chosen instruments are not valid or reliable.
• A representative sample is not available to the researcher.
• The researcher is unsure how to analyze the data that have been gathered.
• The data in hand do not lend themselves to the planned analyses.

Question 10
3 out of 3 points
There are unique challenges associated with conducting research on data that are already
in existence (e.g., historical research). Discuss some of these unique challenges, pointing
out pitfalls the researcher should be careful to avoid.
Answer
Selected
Answer:
The two biggest challenges of historical research are determining the
external and internal evidence of a piece of datum (artifact). Determining
the external evidence is the first priority and involves deciding whether an
artifact is genuine or not. This analysis can be performed with tools such as
carbon dating, hand writing analysis or material analysis. Validating the
genuineness of a historical article in turn validates the research. Once it
has been determined that an article is genuine, the next challenge is to
determine its internal evidence. This involves analyzing what the historical
artifact means. These two types of evaluation are of utmost importance to
historical research, but also pose real challenges to this field of study.

Answer:
Response
Feedback:
When using existing documents or records, it is sometimes difficult to find out
exactly where the documents or records physically exist and exactly
what information is contained in them. This impedes the ability of the
researcher to say for sure whether such sources will shed light on the
research problem. Sometimes obtaining access to existing records or
documents is difficult due to inaccessible location or heavy restrictions
on access.

Question 11
3 out of 3 points
In regard to quantitative research proposals, novice researchers often find it very
challenging and tedious to explain in detail how the data will be analyzed and interpreted
in their study. Explain why it is essential that the researcher not cut corners in this section
of the proposal.
Answer
Selected
Answer:
Correct
Answer:
It is important not to cut corners during the research proposal because it will
not bring out the best in a proposal. By cutting corners it can keep the
reader lost by lacking essential details like precision and logic of the final
document.
Providing a detailed look at this methodology will ensure an efficient and
productive manner in which the data will be analyze and interpreted. This
can serve several purposes. The methodology for this step of the research is
stated prior to the research and therefore out in the open when the research
begins. If there were any contradictions or opposing opinions to the
methodology used then the research would not be held responsible. This
also ensures that the researcher does not forget to include any analyzing or
interpreting techniques that are listed in the methods. The helps the
researcher complete this step without forgetting anything.
By clearly specifying in advance how questionnaires will be scored or other
measurements used, the researcher avoids gathering data that turn out to not
lend themselves easily to quantification. By specifying in advance what
statistical techniques will be used, the researcher avoids a situation in which
the data gathered are not suitable to the planned analysis (e.g., wrong level of
measurement—ordinal, interval, etc.—in the outcome measures, grouping
information not available, sample size too small). By specifying in advance
how the results of statistical tests will be interpreted in light of the research
question, the researcher avoids ending up with results that do not fully or
adequately address the research problem set forth.

In my opinion I would recommend a cover letter for an academic job has a
function similar to one for a business job, but the content differs
significantly in quantity and kind. While the general advice for business
cover letters—such as tailoring your letter for the specific job and selling
your strengths—still applies, a cover letter for an academic position should
be long enough to highlight in some detail your accomplishments during
your graduate education in research, teaching, departmental service, and so
on.
A better approach is to address the needs and interests of the respondent. If
the information in the survey or following from the study might be of
personal interest to the potential respondent, point this out and say how s/he
can gain access to your findings. If the study is linked to attaining goals the
respondent may value (better schools, safer neighborhoods, more efficient
local government, etc.), point this out in the cover letter. At a minimum,
acknowledge the potential respondent’s willingness to invest time in your

A medical researcher is concerned about mistakenly concluding that a new medication is
effective when it really is not. What type of error is the researcher concerned about
making (Type I or Type II)? Describe what the researcher might do to decrease the
likelihood of making that type of error. Discuss ramifications of your suggested approach
for other types of error in the study.
Answer
Selected
Answer:
Correct
Answer:
If the researcher is concerned about mistakenly concluding that a new
medication is effective Type I error (rejecting the null hypothesis when he
should have accepted it). To decrease the probability that he will make a
Type I error the researcher can decrease the risk level of his hypothesis test
from say 0.05 to 0.01. Type II error (accepting a null hypothesis when it
should have been rejected) increases and would not be useful.
The researcher is concerned about making a Type I error: concluding that
there are differences between the medication and placebo groups when
these are really due merely to chance. The researcher can reduce her
chances of making a Type I error by reducing her probability (alpha)
level—from .05 to .01 or even .001, for instance. The more stringent the
probability level, the less likely the researcher will be to make a Type I
error. However, Type I and Type II errors exist in an inverse
relationship. So as the chance of making a Type I error decreases, the
chance of making a Type II error (concluding that the medication is not
effective when, in fact, it is) increases.

This approach was a good by rcognizing the keywords that lead to

online databasis.
Kirby is right that the quality of the journal in which articles are published
is one factor worth noting when making decisions about what to include in
the literature review. However, there were more important distinctions
Kirby should have made before taking that particular step. The keywords
Kirby used in his search were overly general. His list of articles
undoubtedly contains many that are only remotely related to his research
problem, as well as many that are closely related. To maintain appropriate
focus in the literature review, Kirby needs to first narrow his list of articles
to those most relevant to his particular research problem. It may later make
sense to eliminate additional articles from the list on the basis of journal
quality, but that decision is premature at Kirby’s present state.

Question 16
2.5 out of 3 points
Factorial designs allow researchers to study the effects of more than one independent
variable simultaneously. Why is this advantageous? What information can factorial
designs yield that nonfactorial designs cannot?
Answer
Selected
Answer:
Correct
Answer:
Factoial design is advantageous because in many situations it provides a
researcher to examine the two effects of two or more independent variables
in a single study.
This is advantageous because researchers are often interested in more than
one effect on the dependent variable. Oceanographers may want to study
effects related to both water temperature and salinity. Child welfare workers
may want to study the effects of family income, mother’s education level,
and history of abuse on coping ability. The factorial design not only allows
researchers to study these various factors independently, but their
interactions can be studied as well. Studying interactions allows researchers
to investigate the extent to which two or more factors influence each
other. Perhaps whales encounter health problems in warmer water only at
certain levels of salinity. Perhaps parents cope more successfully with stress
when both family income and/or education level surpass a certain
threshold. Or perhaps family income influences coping ability only when
there is no history of abuse.

In a qualitative world, no single, determinable truth exists. Instead, there are

Question 18
2 out of 2 points
Explain “Research usually divides the principal problem into more
manageable subproblems”.
Answer
Selected This characteristic basically explains a standpoint, to break a main research
Answer: problem into several sub problems that when solved can resolve the main
problem.
Breaking down principal problems into small, easily solvable sub problems is
a strategy we use in everyday living.
example:
Driving to town A to town B. The goal is to get from one location to the other
as expeditiously as possible. You soon realize that the problem involves sub
problems such as what route appears to the most direct one and which is the
more important to minimizing travel time.
Correct
Answer: From a design standpoint, it is often helpful to break a main research problem
into several subproblems that, when solved, will resolve the main problem.
Breaking down principal problems into small, easily solvable subproblems is
strategy we use in everyday living. for example, suppose you want to get
from your town to a town 50 miles away. Your principal goal is to get from
one location to the other as expeditiously as possible. You soon realize,
however, that the problem involves several subproblems:
Main problem: how do I get from Town A to Town B?
Subproblems: 1. What is the most direct route?
2. How far do I travel on the highway?
3. Which exit should I take to leave the highway?
What seems like a single question can be divided into at least three smaller
questions that must be addressed before the principal question can be
resolved.

What is a hypothesis?
Answer
Selected
Answer:
Correct
Answer:
A hypothesis is a logical supposition, a reasonable guess, an educated
conjecture. It provides a tentative explanation for a phenomenon under
investigation. It may direct your thinking to possible sources of information
that will aid in resolving one or more sub problems and, as a result, may also
help to resolve the principal research problem.


Question 22
2 out of 10 points
Explain the research cycle.
Answer
Selected
Answer:
Correct
Answer:
The research cycle has 6 steps:
1. Research begins with a problem: an unanswered question in the mind of
the researcher.
2. Research defines the goal in terms of a clear statement of the problem.
3. Research subdivides the problem into appropriate sub problems.
4. Research posits tentative solutions to the problems through reasonable
hypotheses. These hypotheses direct the researcher to appropriate data
5. Research looks for data directed by the hypotheses and guided by the
problem and research methodology. The data are collected and organized.
6. Research interprets the meaning of the data, which leads to a resolution of
the problem, thus supporting or not supporting the hypotheses or providing
an answer to that question that began the research cycle. At this point, one or
more new problems may emerge.

Explain eight different approaches to sampling designs.
Answer
1. Simple random sampling- Simple random sampling is exactly is exactly the
Selected
process just described: Every member of the population has an equal chance
Answer:
of being selected.
2. Stratified random sampling- Has three different layers of distinctly different
types of indiviuals. In stratified random sampling, the researcher samples
equally from one of the layers in the overall population.
3. Proportional stratified sampling- In the simple stratified random sampling
design just described, all strata of the population are essentially equal in size.
4. Cluster sampling- a sample of study through normal randomnization
procedures. It is important that the clusters be as similar to one another as
possible, with each cluster containing an equally heterogeneous mix of
individuals.
5. Systematic sampling- involves sampling selecting individuals, or perhaps
clusters according to a predetermined sequence.
6. Convience sampling- also known as accidental sampling makes no pretense
of identifying a representative subset of a population.
7. Quota sampling- Quota sampling is a variation of convenience sampling. It
selects respondents in the same proportions that they are found in the general
population, but not in random fashion.
8. Purposive sampling- pople or other units are chosen.

in combination distort the data.
Answer:
Studies involving mailed questionaires frequently fall victim to bias without to
researchers awareness. Bias attacks the integrety of facts. It is especially
vicious when it enters surreptitiously into the research system and goes

Question 5
2 out of 2 points
Explain the advantages and disadvantages of face-to-face and telephone interviews,
questionnaires.
Answer
Selected
Answer:
Correct
Answer:
Face to face interviews have the distinct advantage of enabling the researcher
to establish rapport with potential participants and therefore gain their
cooperation. The disadvantage is the time and expense involved may be
prohibitive if the needed interviewees reside in a variety of states, provinces, or
countries.
Telephone interviews are less consuming and less expemsive, and the
researcher has potential access to virtually anyone on the planet who has a
landline telephone or cell phone. The disadvantages of telephone interviews
cannot establish the same kind of rapport that is possible in a face to face
situation, and the sample will be biased to the extent that people without
phones are part of the population about whom the researcher wants to draw
inferences.
Questionaires have an advantage for participants to respond to questions with
some assurance that their responses won't come back to haunt them. Thus,
they may be more truthful than they would be in a personl interview, especially
when addressing sensitive or controversial issues. The disadvantages are: the
majority of people who recieve questionnaires don't return them.
Face-to-face interviews have the distinct advantage of enabling the
researcher to establish rapport with potential participants and therefore
gain their cooperation, thus, such interviews yield the highest response
rates in survey research. Personal interviews also allow the researcher
to clarify ambiguous answers and, when appropriate, seek follow-up
information. However, such interviews take time and so may not be
practical when very large sample sizes are important. And, of course,
the time and expense involved may be prohibitive if the needed
interviewees reside in a variety of states or countries.
Telephone interviews are less time-consuming and less expensive, and
the researcher has ready access to virtually anyone on the planet who
has a telephone.
The researcher cannot establish the same kind of rapport that is
possible in a face-to-face situation and the sample will be biased to the
extent that people without phones are part of the population about
whom the researcher wants to draw inferences.
Questionnaires may save the researcher travel expenses and postage is
typically cheaper that a long-distance telephone call.
However, it has its drawbacks as well. The majority of people who
receive questionnaires don’t return them, and the people who do return
them are not necessarily representative of the originally selected
sample.

If the population size around 500 (give or take 100), 50 % should be
sampled.
If the population size is around 1500, 20 % shold be sampled.
Beyond a certain (about N = 5,000), the population size is almost
irrelevant and a sample size of 400 will be adequate.
For small populations (N<100), there is little point in sampling.

Question 9
2 out of 2 points
Explain the advantages and disadvantages of cross-sectional study and longitudinal
study.
Answer
Cross sectional studies are easier and more expedient to conduct than
Selected
longitudinal studies because the researcher can collect all the needed data at a
Answer:
single time. In contrast. In contrast, a reseacher who conducts a longitudinal
study must collect data over a lengthly period and will almost invariably lose
some participants along the way because the move to unkown locations or
perhaps because they no longer want to participate. In adddition people
respond repeatedly to the same measure instrument, event if the characteristic
being measured hasn;t changed.
Cros sectional studie have disadvantages sucha s the different age groups
sampled may have been raised under different environmental conditions.
Secondly, is that we cannot compute correlations between characteristics of
different age levels.
Correct
Answer:
In a cross-sectional study, people from several different age groups are
sampled and compared. In a longitudinal study, a single group of
people is followed over the course of several months or years, and data
related to the characteristic under investigation are collected at various
times.
Cross-sectional studies are easier to conduct than longitudinal studies,
because the researcher can collect all the needed data at a single time
and doesn’t have to worry about tracking down people who may have
relocated to various points around the globe.
Another disadvantage of longitudinal design is that when people
respond repeatedly to the same measurement instrument, they are likely
to improve simply because of their practice with the instrument, even if
the characteristic being measured hasn’t changed at all.
But cross-sectional designs have their disadvantages as well. For one
thing, the different age groups sampled may have been raised under
different environmental conditions.
A second disadvantage of a cross-sectional design is that we cannot
computer correlations between characteristics at different age levels.
