Detailed explanation-1: -Reliability of the questionnaire is usually carried out using a pilot test. Reliability could be assessed in three major forms; test-retest reliability, alternate-form reliability and internal consistency reliability. These are discussed below. Test-retest correlation provides an indication of stability over time.
Detailed explanation-2: -To be reliable, measurement must be consistent from individual to individual surveyed, across settings and at different times. Consistency of information is essential for making general statements.
Detailed explanation-3: -Reliability refers to how consistently a method measures something. If the same result can be consistently achieved by using the same methods under the same circumstances, the measurement is considered reliable. You measure the temperature of a liquid sample several times under identical conditions.
