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 and validity are both about how well a method measures something: 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: -A measure can be reliable but not valid, if it is measuring something very consistently but is consistently measuring the wrong construct. Likewise, a measure can be valid but not reliable if it is measuring the right construct, but not doing so in a consistent manner.
Detailed explanation-4: -A test can be reliable without being valid. However, a test cannot be valid unless it is reliable. Another way to think of it is that a test can give a consistent, poor result. However, it cannot give a good result unless it is consistent.
Detailed explanation-5: -The purpose of establishing reliability and validity in research is essentially to ensure that data are sound and replicable, and the results are accurate. The evidence of validity and reliability are prerequisites to assure the integrity and quality of a measurement instrument [Kimberlin & Winterstein, 2008].
