If you are doing experimental research, you also need to consider internal and external validity, which deal with the experimental design and the generalizability of results.Ĭontinue reading: The 4 Types of Validity in Research | Definitions & Examples The 4 Types of Reliability in Research | Definitions & Examples Note that this article deals with types of test validity, which determine the accuracy of the actual components of a measure. In quantitative research, you have to consider the reliability and validity of your methods and measurements. Criterion validity: Do the results accurately measure the concrete outcome they are designed to measure?.Face validity: Does the content of the test appear to be suitable to its aims?. ![]() Content validity: Is the test fully representative of what it aims to measure?.Construct validity: Does the test measure the concept that it’s intended to measure?.If a method measures what it claims to measure, and the results closely correspond to real-world values, then it can be considered valid.
