Operational definitions: define abstract constructs in terms of specific procedures and
measures
Variables: events, objects, people or phenomena that vary in amount, degree or kind with
respect to certain aspects
Range restriction: the reduction in the size of validity coefficient due to the selection process
Measurement error: the size of a validity coefficient cannot exceed the reliability of the
measure used to obtain the data
Sampling error: the validity coefficient based on a sample is an estimate of what the
coefficient is in the entire population
Bias: systematic errors in measurement, or inferences made from measurements, that are
