Question

Quizplus · Accepted Answer

The low KR 20 coefficient alpha indicates poor internal consistency reliability of the attitude scale. This means that the items on the instrument are not measuring the same construct consistently, and thus the instrument needs to be revised before it can be considered a reliable measure of tolerance. Therefore, the instrument is an attitude scale, specifically measuring tolerance of software engineers during technology renovations.
