A. Memory score
B. Amount of sleep
C. Participants
D. Researcher
B. Amount of sleep
Remember: IV = what the researcher changes/manipulates.
As study time increases, test scores tend to increase. What type of correlation is this?
Positive correlation
Why: Both variables move in the same direction.
Which statement is a hypothesis?
A. Psychology is interesting.
B. Students who sleep at least eight hours will score higher on a memory test than students who sleep four hours.
C. Why do humans dream?

As the number of absences increases, a student's grade tends to decrease. What type of correlation?
Negative correlation
Why: Variables move in opposite directions.
Researchers repeat another scientist's study to determine whether they get similar results. What is this called?
Replication
Why: Replication helps determine whether findings are reliable.
Which psychologist is strongly associated with behaviorism and operant conditioning?

Test Trap: Think Freud → unconscious → psychodynamic.
Why is random assignment useful in an experiment?
A. It guarantees the hypothesis is correct.
B. It makes every participant identical.
C. It helps create similar groups and reduces preexisting differences.
D. It eliminates the need for a control group.
C.
Why: Random assignment helps researchers determine whether the independent variable actually caused differences between groups.
Which represents the strongest correlation?
A. +0.24
B. -0.91
C. +0.67
D. -0.48
B. -0.91
Strength depends on how close the number is to 1.00 or -1.00, NOT whether it's positive or negative.
A researcher gives 1,000 teenagers a questionnaire asking about their social-media use and stress. What research method is being used?

B. Survey
C. Naturalistic observation
D. Case study
B. Survey
Psychology eventually developed from which two major fields of study?

C. Evolutionary
D. Cognitive

A. Survey
B. Correlational study
C. Case study
D. Experiment
D. Experiment
TEST TRAP: To establish cause and effect, think experiment.
Researchers find that students who sleep more tend to have higher grades. Can they conclude that sleeping more causes higher grades?
A. Yes
B. No
B. NO!
Why? Correlation shows a relationship, not cause and effect. Other variables could influence both sleep and grades.
