C
Interpretation should consider the direction and size of the effect and relevant uncertainty.
D
A p-value gives the probability that the research hypothesis is true.
E

A survey about all university students receives many responses from volunteers in one online student group. Which conclusion is most defensible?

A
The results are necessarily representative if the number of respondents is large.

The estimates may be biased; the researchers should describe recruitment and avoid assuming the group represents the population.
C
Random assignment to survey conditions would make the sample representative.
D
The estimates are unbiased as long as the survey used fixed-response questions.

A researcher wants to measure students’ self-perceived academic engagement. Which approach best operationalizes this concept?

A
Use attendance as a complete measure of every aspect of academic engagement.
B
Use a validated questionnaire about self-perceived engagement and explain why it fits that aspect of engagement.
C

D
Combine unrelated measures without explaining how they represent the concept.

D
The sample is representative as long as every respondent received the same questionnaire.
