D)discrete variables only.

Question

Quizplus · Accepted Answer

Standard deviation is a measure of dispersion that calculates the amount of variation or spread of a set of data values from their mean. As it involves mathematical operations such as addition, subtraction, multiplication, and division, it is appropriate for interval-ratio level variables which have numerical values and support arithmetic operations. Nominal level variables cannot support arithmetical operations, discrete variables may not be continuous, and non-continuous variables are not suitable for calculating standard deviation.
