As of this understanding, the two should be considered in every research process since it is only then that the findings can be reliable and valid. Besides, researchers can always improve the integrity and validity of their findings by ensuring that their practices are based on the principles of validity and dependability. With this in mind, the paper will define and examine the concepts of reliability and validity as well as analyze their relationship and how they are measured.
Definition and Examination of The Concepts of Validity and Reliability
Reliability refers to the stability, consistency, and repeatability of research instruments. According to Remler and Ryzin (2022), reliability examines how easily research findings can be reproduced or repeated. Reliability means that if an instrument is used to make tests severally, the results should be the same. On the contrary, if the results differ, the instrument is unreliable and probably unrelated to the measured concepts. A good example of unreliable findings is when one uses a broken thermometer, which gives different results every time it is used in the same environment and under the same conditions. What is conceived from this is that reliability in research is crucial since the results should represent actual findings rather than result from chance or measurement mistakes.
On the other hand, validity denotes that the test instrument being used accurately measures what it is meant to ...
