b.I'm trying to measure happiness by my scale really measures calmness.
c.I'm sometimes in a good mood and sometimes in a bad mood when I meet with participants.
d.Both a and c.
e.All of the above.
Explanation / Answer
Correct answer is option d (Both a and c)
Both a (some of my participants are in bad moods and some are in good moods) and c (I'm sometimes in a good mood and sometimes in a bad mood when I meet with participants) will have an impact on the reliability scale.
The first option a, denotes to test retest reliability as the results would change depending on the mood of the participants. Option c, relates to inter-rater reliability where the results would change depending on the moods of the assessor and if two assessors assess the same test and if it brings different results that would be a reliability flaw as well.
