A claim about two variables, in which the value (level) of one variable is said to vary
systematically with the value of another variable, such that when one variable
changes, the other variable tends to change also.

,An empirical form of measurement validity that establishes the extent to which a
measure is correlated with a behavior or concrete outcome that it should be related
to.

criterion validity
A quantitative measurement scale whose levels represent a ranked order, in which it is
unclear whether the distances between levels are equal (e.g., a 5-star rating scale).

variable.
