The three types of validity measure the truthfulness and accuracy of tests in many different ways. Within the domain of psychological research methods, any errors in the reliability and validity of a test or experiment are very detrimental to the value of the research. Methods of estimating reliability and validity are usually split up into different types.

Reliability refers to a study's replicability, while validity refers to a study's accuracy. Your weighing machine might be malfunctioning. The validity and reliability of the scales used in research are important factors that enable the research to yield healthy results. Repeatability or test-retest reliability is defined as 'closeness of the agreement between the results of successive measurements of the same measure and carried out under the same conditions' ( Taylor and Kuyatt, 1994, 14), which is guaranteed for any deterministic DL model.
