Internal Validity: Internal quality is the extent to which the researcher can make the claim that no other variables besides the one, under study, caused the result. Exterior Validity: External validity is the extent to which results of an analysis can be generalized to the real-life cases, in particular.
To ensure the internal validity of the study, teachers and students are matched on variables, relevant for the study's outcome. To evaluate the intervention, the
Internal validity is the level up to which an experiment or research is free from errors. Errors might include variations in measurement because of the independent variable. It is a degree up to which outcomes of the research could be inferred to the real-world on a large scale. Internal validity is a scientific concept that addresses the relationship between two variables. It refers to the extent that a study can rule out or make unlikely alternate explanations of the internal validity) we are making the experiment more and more artificial and thereby it’s generalizability (external validity) suffers. An exception would be in reference to specific control techniques e.g. the balance technique would allow for more generalizability than would the eliminate or hold constant techniques Internal Validity: Internal quality is the extent to which the researcher can make the claim that no other variables besides the one, under study, caused the result.

It is one of the most important properties of scientific studies, and is an important concept in reasoning about evidence more generally. Factors That Improve Internal Validity Blinding: Participants—and sometimes researchers —who are unaware of what intervention they are receiving (such as by Experimental manipulation: Manipulating an independent variable in a study (for instance, giving smokers a cessation Random selection: 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.
