STATISTICS FOR THE BEHAVIORAL

PAPER EXAM PREP QUESTIONS AND
ANSWERS GUARANTEED TO PASS
◉ Matched-Subjects Design
Answer: Each individual in one sample is matched with an individual
in the other sample. the matching is done so that the two individuals
are equivalent (or nearly equivalent) with respect to a specific
variable that the researcher would like to control.
◉ Factor
Answer: The independent variable.
◉ Levels
Answer: The different groups or treatments or conditions.
◉ Testwise Alpha Level
Answer: The risk of a Type I Error, or alpha level, for an individual
hypothesis test.
◉ Experiment-wise Alpha Level
, Answer: The total probability of a Type I Error that is accumulated
from all of the individual tests in the experiment. Typically, the
experiment wise alpha level is substantially greater than the value of
alpha used for any one of the individual tests.
◉ Pot Hoc Tests
Answer: additional hypothesis tests that are done after an ANOVA to
determine exactly which mean differences are between groups
◉ Main Effect
Answer: The mean differences among the levels of one factor for
factorial ANOVA.
◉ Interaction
Answer: When the effect of one factor depends on the different
levels of a second factor.
◉ What do correlations do?
Answer: 1. Prediction
2. Validity
3. Reliability
4. Theory Verification
