1. A researcher conducts a study to determine if caffeine
affects memory. Participants are randomly assigned to a
caffeine group or a placebo group. The independent variable
is:
A) Memory test scores
B) Caffeine (or placebo)
C) The participants
D) The time of day
Answer: B – The independent variable is manipulated by the
researcher.
Rationale: The independent variable is caffeine (present vs.
absent); memory test scores are the dependent variable.

2. A correlation coefficient of -0.85 indicates:
A) A strong positive relationship
B) A weak negative relationship
C) A strong negative relationship
D) No relationship
Answer: C – The negative sign indicates inverse relationship; the
magnitude (0.85) indicates a strong relationship.
Rationale: Values range from -1.0 to +1.0; closer to ±1 =
stronger correlation.
3. Which research method would be most appropriate to study
the natural behavior of children on a playground?
A) Controlled experiment
B) Naturalistic observation
,Page 3 of 136
C) Survey
D) Case study
Answer: B – Naturalistic observation involves observing subjects
in their natural environment without interference.
Rationale: It provides high external validity but low control over
variables.
4. In a double-blind experiment, neither the participants nor
the:
A) Experimenter knows who is in the control group.
B) Participants know the hypothesis.
C) Experimenter knows the independent variable.
D) Participants know they are in a study.
Answer: A – Double-blind means both the researchers and
participants are unaware of group assignment.
Rationale: This prevents experimenter and participant bias.

5. A researcher finds that as the number of hours spent
studying increases, exam scores increase. This is an example
of:
A) A negative correlation
B) A positive correlation
C) No correlation
D) A causal relationship
Answer: B – Both variables move in the same direction (increase
together).
Rationale: Correlation does not imply causation.
6. The “placebo effect” refers to:
A) Improvement due to the actual treatment.
B) Improvement due to participants’ belief in the treatment.
