In the social sciences it is very difficult to get the most reliable results. Which of the following can affect the reliability of results?

1.The wording of the questions

2.The physical setting of the interaction

3.The mood of the respondent

4.The mood of the interviewer

5.The nature of the interaction

6.The regression effect of an instrument

A1, 2, 3, 5 and 6

B2, 3 and 5

C1, 2, 3, 4, 5 and 6 ✓ Correct

D1, 3, 4 and 5

Correct answer: (C) 1, 2, 3, 4, 5 and 6

Explanation

Question wording, physical setting, respondent mood, interviewer mood, interaction nature and instrument regression can all lower reliability.

Ambiguous wording produces inconsistent responses.

The physical setting and the respondent's mood shift answers between sittings.

The interviewer's mood and the interaction's nature bias the exchange.

An instrument's regression effect drags extreme scores toward the mean on retest.

Reliability means consistency of results across repeated measurement.
