When there is no error in measurement,reliability is ____.

D)equal to the inverse of the variability of the distribution

Question

Quizplus · Accepted Answer

Reliability refers to the consistency or stability of a measure over time or across different contexts. If there is no error in measurement, then the measure is perfectly reliable, meaning that it produces identical results every time it is used. This perfect reliability is represented by a reliability coefficient of 1, which is the answer choice B. Option A is incorrect as reliability cannot be 0 if there are no errors. Option C and D are incorrect as they are not necessarily true when there are no errors in measurement - they depend on the actual variability of the distribution.
