Question

question 30 (2 points)
the extent to which a questionnaire or interview yields the same answers from the same subjects when they are questioned two or more times is called ______.

a) validity

b) reliability

c) ecological fallacy

d) spurious association

Explanation:

• Option a: Validity refers to how well a measure assesses what it is intended to assess, not consistency over repeated measurements.
• Option b: Reliability is defined as the consistency of a measure, such as a questionnaire or interview, in producing the same results when administered to the same subjects multiple times. This matches the description in the question.
• Option c: Ecological fallacy is an error in inference from group - level data to individual - level data, not related to the consistency of survey/ interview responses.
• Option d: Spurious association is a relationship between two variables that appears causal but is not, due to a confounding variable, and is not related to the consistency of measurements.

Answer:

b) reliability
