“Survey Says!”
[RETURN THE ENTIRE STAPLED SURVEY EACH DUE DATE]
PART Ia
SCORE: ___/10pts
To demonstrate several statistical and methodological issues, gather data on a sample size of
20 participants (10 female and 10 male). Do NOT ask both members of a couple as this would
violate the assumption of independence associated with the statistical test we will use later
in the semester. For standardization purposes, be sure to ask the question without changing
the wording of the question for each participant. Record your data below.
TARGET QUESTION: “How many pairs of shoes do you own?”

Follow the steps to hypothesis testing and conduct a two-sample t-test comparing
the female and male participants (yes this study is correlational, but we are NOT
performing a correlation because we are comparing males and females instead):

PART V SCORE: ____/20pts
Check your calculations. Enter your raw data into SPSS. Attach your printout
(5pts), and discuss your results below:
1. Were the results from PART IV and V the same? If not, explain why (1pt).
2. Were the SPSS results significant (i.e., What does this mean about your
variables) (2pts).
3. Report your results statistically(2pts):_________________________________
4. What were the limitations of the study (i.e., what could you have done
differently to make this a better/more valid research study)? (5pts)
5. What are the implications (NOT CONCLUSIONS!!!) of the study (i.e., what do the
results mean for the rest of the world; what can we possibly do with this
information at present or in future analysis)? (5pts)
PART VI
JOURNAL ARTICLE
To familiarize you with research in the behavioral and social sciences and to
assist you with finding supporting research for Part VII, you are required to find a
journal article, print a copy, and answer a few questions. The article must be an
empirical source, meaning that the research was conducted by those who have
written the article. The article must also contain multivariate statistics, including but
not limited to those discussed in your text such as a correlation, t-test, ANOVA, or
chi-square. If you do not understand the article, DON’T use it!
Part VI of your survey answers the “why” questions you’ll address in Part VII;
for example, “why” did you decide on your particular hypothesis for this survey or
“why” did you believe you did/didn’t find significant results? In other words, your
assignment is to find an article that will support your hypothesis and/or findings of
your shoe survey.
Finding an Article:
Locate the EBSCO Host database from the BC Library Homepage. Select the
“Psychology and Behavioral Sciences Collection” from the initial database list in
EBSCO Host. Type in your selected topic terms (one word per line). Before hitting the
search button, scroll down the page and select “Full Text” and “Peer Reviewed” to
increase the likelihood of locating an empirical journal source that is readily available
to print. Once you’ve selected the search button, the program will generate a list of
article titles that you can browse through. HINT: remember that we are trying to see
if there is a difference between the GENDERS and the number of SHOES owned. Maybe
there are differences in the GENDERS and the emphasis they place on APPEARANCE.
Maybe there are differences in CONSUMERISM between the GENDERS. Maybe this only
applies to certain ETHNICITIES or CULTURES.
Printing your Article:
Be aware of the number of pages before you print. Some articles can be as many as 40
pages! To see a copy of the full text, select the PDF icon or the HTML icon below the
article title (not the article title itself!). I recommend selecting the HTML icon simply
because it gives you an option to print your article in APA format.
Journal Article Questions:
Answer the following questions with regard to your article. If you cannot answer all of
the questions listed below, select another research article. Include as much
information in your own words as possible. Do not copy sections of your journal
article word for word! I WILL be evaluating you for grammar and punctuation so
proofread your responses!

PART VII SCORE: ____/50pts
At this point in the research process, you’ve learned to define your variables and
describe your sample and population (Part I), calculate the descriptive statistics
for your data (Parts II & III), analyze your data using inferential procedures (Parts
IV & V), discuss the results, limitations, and implications of your research (Part V),
and find a source to support your hypotheses and/or findings (Part VI).
Now it is time to combine all those processes together into a journal summary (no
title page or abstract needed) by completing the following steps:
1)
Based on the feedback you’ve received on Parts I-VI, summarize your
research in your own words. Each section (Introduction,
Methods/Procedures, Results, Discussion) will be approximately one
paragraph of your summary for a total of 4 paragraphs] and should address
the content listed on the evaluation worksheet.
2)
Type your summary in APA format (excluding a title page and abstract),
complete with at least two sources with in-text citations (using the
author(s) last name, year, and/or page #) in the body of your paper and
listed on a separate reference page. Use 1" margins, double spacing, and 12
point font. Your summary should be at least total three pages (2 content
pages and 1 reference page). You must use the statistical terminology we’ve
discussed in lecture and found in your text to receive full credit for this
research assignment.
3) Once you have completed your typed paper return your assignment in this
order:
