Quizplus · Accepted Answer

Measurement validity refers to the degree to which a measurement instrument accurately measures what it is supposed to measure. A high correlation between the instrument and the predicted outcomes indicates that the instrument is valid, as it is accurately predicting the desired outcomes. Internal validity refers to the accuracy of causation within a study, reliability refers to the consistency of results within a study or across studies, and statistical significance refers to the probability of obtaining a result due to chance. While these factors are related to validity, they do not necessarily indicate validity on their own.
