To measure the criterion validity of a test, researchers must calibrate it against a known standard or against itself. Comparing the test with an established measure is known as concurrent validity; testing it over a period of time is known as predictive validity. It is not necessary to use both of these methods, and one is regarded as sufficient if the experimental design is strong. One of the simplest ways to assess criterion related validity is to compare it to a known standard. A new intelligence test, for example, could be statistically analyzed against a standard IQ test; if there is a high correlation between the two data sets, then the criterion validity is high. This is a good example of concurrent validity, but this type of analysis can be much more subtle.
