Correlation is used to examine the relationship between two variables, and in psychometric testing, it is often used to examine the relationship between different measures. By examining the correlation between measures, a psychometrician can determine the extent to which the measures are reliable (consistent over time) and valid (measuring what they are intended to measure). Therefore, the important aspects of the development of measures that are examined using correlation are reliability and validity.
