Therefore, this highlights that validity and reliability guide the general outcome of a research process. Any evidence to be considered should cover the reliability of the measure.
Validity refers to a judgment pegged on several kinds of evidence.
Since reliability emphasizes the general consistency of the measure of a study, its primary role is to ensure that the research is credible and ensures that the research process is dependable to provide accurate results. Reliability and validity are the two criteria used by researchers to evaluate research measures. Validity also enables the researcher is utilizing questions that truly analyze the concerns of importance. For instance, internal validity focuses on showing a difference. But there are further differences between the two as well. For example, adopting it guides the research to have practical and reliable questions. The essential difference between internal validity and external validity is that internal validity refers to the structure of a study (and its variables) while external validity refers to the universality of the results. The leading role of validity in conducting applied research is to help the researcher determine the specific survey questions to be utilized in the study. An applied research’s validity is regarded as the extent to which it analyzes what ought to be measured. More specifically, reliability is concerned about the general consistency, while validity emphasizes the accuracy of a given measure (Cohen et al., 2017). Validity and reliability are among the primary concepts used by researchers to assess the quality of research.
