Internal validity refers to the extent to which the experimental design accurately reflects the true relationship between the variables being tested. When researchers have more control over the experimental conditions, they are better able to eliminate extraneous variables that could interfere with their results. This increases the likelihood that the results accurately reflect the relationship between the variables being studied, thus increasing internal validity.
