In psychometrics, predictive validity is the extent to which a score on a scale or test predicts scores on some criterion measure. [1] [2]For example, the validity of a cognitive test for job performance is the correlation between test scores and, for example, supervisor performance ratings.
Another study found that adding the HEXACO honesty-humility factor to personality measures improves predictive validity for both self- and other-reports of personality, and that simply creating an honesty factor from the FFM measures improves predictive validity for some measures (mainly social adroitness and sexuality measures), but not all (e ...
An example of predictive validity is a comparison of scores on the SAT with first semester grade point average (GPA) in college; this assesses the degree to which SAT scores are predictive of college performance. [5]
The positive predictive value (PPV), or precision, is defined as = + = where a "true positive" is the event that the test makes a positive prediction, and the subject has a positive result under the gold standard, and a "false positive" is the event that the test makes a positive prediction, and the subject has a negative result under the gold standard.
Concurrent validity is a type of evidence that can be gathered to defend the use of a test for predicting other outcomes. It is a parameter used in sociology, psychology, and other psychometric or behavioral sciences. Concurrent validity is demonstrated when a test correlates well with a measure that has previously been validated. The two ...
Psychometrics is a field of study within psychology concerned with the theory and technique of measurement.Psychometrics generally covers specialized fields within psychology and education devoted to testing, measurement, assessment, and related activities. [1]
For example, Jensen’s oldest daughter came to him when she was about 6 years old and complained that she had fewer dresses than her younger sister. He pointed out to her that her sister was ...
Incremental validity is a type of statistical validity that assesses whether a new psychometric assessment has more predictive ability than existing methods of assessment. [1] It seeks to determine whether the new assessment adds information that cannot be obtained with simpler, already existing methods.
