Validity and Reliability
The scientific method involves the classification of events or objects into categories. The similarities and differences between categories are then assessed, and results then analyzed. Besides, the variations in characteristics between members of a specific group are assessed. In this way, generalizations are discovered, tested, and formulated to describe a specific set of events or groups of objects. A system of measurement is, therefore, critical for the accomplishment of the above-mentioned tasks (Mason, 2017). In theory, if a set of rules is established, it is possible to measure any event or object. The rules set for a specific measurement tool influence the tool’s validity and reliability. A researcher is tasked with the responsibility of establishing the criteria by which an event or object is distinguished from another. Also, the researcher must assign the weights each of the distinctions will carry. The establishment of validity and reliability determines a study's rigor and the applicability of results and findings identified in real-life situations.
