Validity refers to how accurately a method measures what it is intended to measure. Replication is when a study can be done again and the same general results are found. 2) specific purposes. Validity refers to how appropriate the interpretations of a test score are for the purpose intended. For example, test on a Monday, then again the following Monday. WebWhat Is Internal Validity This phrase refers to the degree of confidence that a causal relationship exists between the treatment and outcome differences.
