1. Validity refers to how accurately a method measures what it is intended to measure. a) Define criterion validity. b) Describe and evaluate the TWO (2) types of criterion validity with appropriate examples.(elaborate with proper info and based on pasychology format )

Criterion validity is evaluated by determining whether a measure is associated in an expected way with some other measure. If both variables are measured at the same point in time, the resulting validity is referred to as:Question 10Select one:a.Predictive validity.b.Content validity.c.Item validity.d.Construct validity.e.Concurrent validity.

__________ refers to consistency in measurement.A.ReliabilityB.ConceptC.VariableD.Validity
