A psychological test is a standardized measure of a sample of a person"s behaviour. Responses represent a sample of your behaviour. Personality tests they measure various aspects of personality, including motives, interests, values and attitudes. Content validity it refers to the degree to which the content of a test is representative of the domain its suppose to cover is evaluated with logic than statistics. Criterion-related validity is estimated by correlating subjects scores on a test with their scores on a independent criterion of the trait assessed by the test. The first crude efforts to devise intelligence tests were made by sir. Francis galton, who wanted to show that intelligence is inherited. Galton is also known for inventing correlation and percentile test scores. Modern intelligence testing began with the work of alfred binet, a french psychologist who published the first useful intelligence test in 1905. Binets scale measured a child"s mental age.
