A test has this type of validity if it is useful for predicting performance or behavior in another situation (past, present, or future).
What are the four types of validity?Table of contents. Construct validity.. Content validity.. Face validity.. Criterion validity.. What is reliability validity?Reliability and validity are both about how well a method measures something: Reliability refers to the consistency of a measure (whether the results can be reproduced under the same conditions). Validity refers to the accuracy of a measure (whether the results really do represent what they are supposed to measure).
What type of validity is determined by finding the correlation between what type of scores?Concurrent validity can usually be established by calculating the correlation between scores obtained from the instrument under investigation with scores from the criterion. Such a correlation is referred to as the validity coefficient. The validity coefficient is a standardize measure that ranges from -1 to 1.
