4/29/2023 0 Comments Test retest reliability psychologyRandom errors are the chance factors that can distort the true score and are inversely proportional to the degree of reliability. Measurement error can be random or non-random. Reliability is majorly an empirical issue concentrated on the performance of an empirical measure. Reliability = True score/ (True score + Errors) In theory, reliability refers to the true score variance to the observed score variance. Four major ways of assessing reliability are test-retest, parallel test, internal consistency, and inter-rater reliability. Reliability, thus, is a matter of degree. This consistency is what we refer to as reliability. At the same time, we can and should expect consistent results on repeated measurement from a good experiment, test, or instrument. Even repeated measures of the same characteristics for the same individual might not duplicate themselves. However, the measurement of any phenomenon invariably contains a certain amount of chance error. Reliability, fundamentally, concerns the extent to which a measure, an experiment, or test yields the same results on repeated trials.
