Detailed explanation-1: -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.

Detailed explanation-2: -Reliability refers to the consistency of a measure (whether the results can be reproduced under the same conditions). Validity refers to the accuracy of a measure (whether the results really do represent what they are supposed to measure).

Detailed explanation-3: -Reliability refers to the extent that the instrument yields the same results over multiple trials. Validity refers to the extent that the instrument measures what it was designed to measure.

Detailed explanation-4: -Description. Internal consistency is a measure of reliability. Reliability refers to the extent to which a measure yields the same number or score each time it is administered, all other things being equal (Hays & Revicki, 2005).

Detailed explanation-5: -Reliability is consistency across time (test-retest reliability), across items (internal consistency), and across researchers (interrater reliability). Validity is the extent to which the scores actually represent the variable they are intended to. Validity is a judgment based on various types of evidence.
