You must control extraneous validity to establish internal validity. Confounding refers to a scenario where other variables you are not investigating enter the picture and distort the conclusion of an experiment. So what is the difference between internal validity and external validity? (a) What is Paul's annual disability benefit? Maturation This is the impact of time as a study variable. Confounding is the presence of a third variable in an experiment. internal consistency reliability The extent to which the items of a test "hang together" (most often assessed by computing Cronbach's alpha). In simple terms, validity refers to how well an instrument as measures what it is intended to measure. A researchs primary goal is to make inferences about how things work based on study results.
