MANAGEMENT

Detailed explanation-1: -Reliability is the degree to which an assessment tool produces stable and consistent results. Test-retest reliability is a measure of reliability obtained by administering the same test twice over a period of time to a group of individuals.

Detailed explanation-2: -Reliability refers to the consistency of a measure. Psychologists consider three types of consistency: over time (test-retest reliability), across items (internal consistency), and across different researchers (inter-rater reliability).

Detailed explanation-3: -Test-retest reliability measures the consistency of results when you repeat the same test on the same sample at a different point in time.

Detailed explanation-4: -Reliability refers to the consistency of a measure. 1 A test is considered reliable if we get the same result repeatedly. For example, if a test is designed to measure a trait (such as introversion), then each time the test is administered to a subject, the results should be approximately the same.

Detailed explanation-5: -Reliability is consistency in measurement over repeated measures. Reliable measures are those with low random (chance) errors. Reliability is assessed by one of four methods: retest, alternative-form test, split-halves test, or internal consistency test. Validity is measuring what is intended to be measured.
