Jonah has developed a new scale to measure tolerance of software engineers during technology renovations. He selects a sample of software engineers and administers the draft instrument to them and calculated a KR 20 of .45. Given what you know about this type of measurement, please answer the following questions.
-Given the KR 20 value, which can you conclude about this instrument?
A) It demonstrates high reliability
B) It demonstrates sound reliability
C) It demonstrates average reliability
D) It demonstrates inadequate reliability

Question

Quizplus · Accepted Answer

A KR 20 value of .45 indicates inadequate reliability. KR 20 values range from 0 to 1, with a score of 1 indicating perfect reliability. Scores closer to 1 indicate higher reliability, while scores closer to 0 indicate lower reliability. In this case, the KR 20 value of .45 is quite low, indicating that the instrument is not very reliable.
