ROUND-ROBIN:
CREATE AN EXPERIMENT SCENARIO AND GIVE AN
EXAMPLE OF EACH OF THE FOLLOWING CONCEPTS…

Control group
IDENTIFY THE FOLLOWING CENTRAL TENDENCIES:

1. What is “range” as in measures of variation?
2. What is the purpose of standard deviation?
3. Look at Table 2.4 on page 39 to review the equation for
standard deviation. (Rarely will you be required to
compute a standard deviation problem on the AP Psych
Exam…(i.e. once every 4 or 5 years).
4. What is statistical significance? Why is it important in
correlational (experimental) studies?
ETHICS IN RESEARCH
1. What things should be completed/done BEFORE
a research study begins in regards to ethics?
2. What things should be ensured DURING a
research study to ensure proper ethics?
3. What things should be completed/done AFTER a
research study in regards to ethics?
FRQ PRACTICE:
Imagine that you are a sports psychologist interested in
the usefulness of a new visualization technique that has
been developed for Olympic divers. You have decided to
conduct an experiment to determine if the technique is
effective.
Discuss the importance of each of the following in
regard to the experiment you are designing: population,
sample, hypothesis, independent variable, dependent
variable, operational definitions, control group, random
assignment, and replication.
GRADING RUBRIC FOR THE PREVIOUS FRQ:
Point 1- Population: The student must make clear that the population is the group of
individuals that the participants are drawn from. In this case, the population is Olympic
divers (or some subset of Olympic divers).
Point 2 - Sample: The student must recognize that the sample is the group of Olympic divers
that is selected for this experiment. The sample must be random so the results of the
experiment can be generalized to the population.
Point 3 - Hypothesis: The student must explain that the hypothesis is the statement of
expectation about the outcome of the experiment. In this case, the hypothesis is that the new
visualization technique will produce better dives. The student may state the null hypothesis,
such as: “There is no difference between groups of Olympic divers.” Students must state the
hypothesis for this particular experiment; a basic definition of “hypothesis” alone should not
earn the point.
GRADING RUBRIC CON…
Point 4 – Independent variable: The student must be aware that the independent
variable is the variable manipulated by the experimenter. In this case, the IV is
whether or not a diver is taught the new visualization technique. Students must state
the independent variable for this particular experiment; a basic definition of
“independent variable” alone should not earn the point.
Point 5 – Dependent variable: The student must be aware that the dependent
variable shows the effect of the independent variable. In this case, the dependent
variable is the quality of the dives. Again, students must state the dependent
variable for this particular experiment to earn the point.
Point 6 – Operational definitions: To earn this point, the student must explain
exactly how the dependent variable will be measured. The clearest way to do this
is with diving scores.
GRADING RUBRIC CON…
Point 7 – Control group: The student must explain the need for a group to which results of
the visualization group may be compared. In this case, the control group would be a
similar group of divers that is not trained in the new technique.
Point 8 – Random assignment: The student must understand the importance of randomly
assigning participants to the visualization and control groups. This allows the experimenter
to assume that the only difference between the divers in the two groups is whether or not
they are taught the visualization technique.
Point 9 – Replication: The student must explain that experimental results are not fully
accepted until the experiment is repeated. If the experiment cannot be replicated, the
results were probably caused by chance instead of by the independent variable.
