In psychology, discriminant validity tests whether concepts or measurements that are not supposed to be related are actually unrelated.. Campbell and Fiske (1959) introduced the concept of discriminant validity within their discussion on evaluating test validity.They stressed the importance of using both discriminant and convergent validation techniques when assessing new tests. How well a study's findings can be applied to other people and circumstances. Internal and external validity are two parameters that are used to evaluate the validity of a research study or procedure. Accordingly, tests wherein the purpose is unclear have low face validity (Nevo, 1985). Which of the following entities is not a product: All of the above are products (people, places, ideas/causes) All sciences are built on systems of constructs and their interrelations. Validity refers to the degree to which a measure accurately measures the specific construct that it claims to be measuring. The conclusions drawn from the experimental results may not accurately reflect what has gone on with the experiment itself, Extent to which we can generalize findings to real-world settings. For example, there must have been randomization of the sample groups and appropriate care and diligence shown in … “Could there be an alternative cause, or causes, that explain my observations and 2. measurement in which numbers are assigned to data on the basis of some order (for example, more than, greater than) of the objects.
