Most reliability coefficients,regardless of the specific type of reliability they are measuring,range in value from
A) -1 to +1.
B) 0 to 100.
C) 0 to 1.
D) negative infinity to positive infinity.

Question

Quizplus · Accepted Answer

Most reliability coefficients range in value from 0 to 1, with higher values indicating greater reliability. Negative values would not make sense as it would indicate a negative relationship between the items being measured, and values greater than 1 are not possible as they would suggest that the measure is more accurate than theoretically possible. A range of 0 to 100 is possible but less commonly used for reliability coefficients. Negative infinity to positive infinity is also not possible as reliability coefficients cannot be negative and there is a theoretical upper limit to the reliability of any measure.
