More specifically, validity applies to both the design and the methods of your research.Validity in data collection means that your findings truly represent the phenomenon you are claiming to measure. Valid claims are solid claims.Reliability and validity are concepts used to evaluate the quality of research. They indicate how well a method, technique or test measures something. Reliability is about the consistency of a measure, and validity is about the accuracy of a measure.The conclusions you draw from your research (whether from analyzing survey, focus groups, experimental design, or other research methods) are only useful if they’revalid. … Validity is used to determine whether research measures what it intended to measure and to approximate the truthfulness of the results.Internal Validity is the approximate truth about inferences regarding cause-effect or causal relationships. Thus, internal validity is only relevant in studies that try to establish a causal relationship. It’s not relevant in most observational or descriptivestudies, for instance.
