Q1.
A researcher wants to study the effect of a new Christian devotional program on anxiety
levels. She randomly assigns participants to either the devotional program or a waitlist
control group and measures anxiety before and after. Which of the following best
describes the primary strength of this design?
A. It allows the researcher to establish a B. It ensures high external validity because
cause-and-effect relationship between the the sample is randomly assigned.
devotional program and anxiety.
C. It eliminates the need for informed D. It guarantees that the results will
consent since the program is religious in generalize to all Christian denominations.
nature.
Correct: A - It allows the researcher to establish a cause-and-effect relationship between
the devotional program and anxiety.
Rationale:Random assignment to conditions is a hallmark of true experimental design,
allowing causal inferences about the effect of the devotional program on anxiety. The other
options misstate the benefits of random assignment or wrongly suggest ethical exemptions or
universal generalizability.
Why the other answers are wrong:
B. Random assignment primarily enhances internal validity, not external validity; generalizability
depends on sampling and other factors.
C. Informed consent is required regardless of the religious nature of the intervention, per APA
ethics code.
D. Results from a single study cannot guarantee generalizability to all Christian denominations;
that would require diverse sampling and replication.

ed.). Cengage. Chapter 6.
Q2.
Which of the following is the best example of a quasi-experimental design?
A. Randomly assigning participants to a B. Comparing anxiety levels of students who
gratitude journaling condition or a neutral voluntarily attend a prayer group versus
writing condition. those who do not.
C. Surveying a random sample of church D. Conducting a double-blind study on the
attendees about their political views. effects of a new antidepressant medication.
Correct: B - Comparing anxiety levels of students who voluntarily attend a prayer group

, Section A - THE Scientific Method AND Psychological Research
versus those who do not.
Rationale:A quasi-experimental design lacks random assignment; comparing self-selected
groups (prayer group vs. non-attenders) fits this definition. The other options involve random
assignment (true experiment) or are purely descriptive/correlational.
Why the other answers are wrong:
A. This is a true experiment because participants are randomly assigned to conditions.
C. This is a descriptive survey, not an experiment or quasi-experiment.
D. This is a true experiment with random assignment and blinding.

Q3.
A researcher reports a Cronbach's alpha of 0.45 for a new scale measuring spiritual
well-being. What does this indicate about the scale?
A. The scale has high internal consistency B. The scale has low internal consistency
and is ready for use. and may need revision.
C. The scale has strong test-retest reliability. D. The scale is valid but not reliable.
Correct: B - The scale has low internal consistency and may need revision.
Rationale:Cronbach's alpha assesses internal consistency; values below 0.70 are generally
considered unacceptable, indicating poor interrelatedness among items. Thus, the scale likely
needs revision to improve reliability.
Why the other answers are wrong:
A. Alpha of 0.45 is low, not high; it suggests poor internal consistency.
C. Cronbach's alpha measures internal consistency, not test-retest reliability.
D. Reliability is a prerequisite for validity; a scale cannot be valid if it is not reliable.

(6th ed.). Cengage. Chapter 4.
Q4.
In a study examining the relationship between church attendance and life satisfaction, a
researcher finds a Pearson r of +0.62. Which of the following is the most accurate
interpretation?
A. Increased church attendance causes B. There is a moderate positive correlation;
increased life satisfaction. as church attendance increases, life
satisfaction tends to increase.
C. There is a strong negative correlation D. Church attendance explains 62% of the
between the variables. variance in life satisfaction.
