 Rikici da zargi 
Because psychometrics is based on latent psychological processes measured through correlations, there has been controversy about some psychometric measures. [<span title="This citation requires a reference to the specific page or range of pages in which the material appears. (November 2010)">page<span typeof="mw:Entity">&nbsp;</span>needed</span>] Critics, including practitioners in the physical sciences, have argued that such definition and quantification is difficult, and that such measurements are often misused by laymen, such as with personality tests used in employment procedures. The Standards for Educational and Psychological Measurement gives the following statement on test validity: "validity refers to the degree to which evidence and theory support the interpretations of test scores entailed by proposed uses of tests". Simply put, a test is not valid unless it is used and interpreted in the way it is intended.
