Internal validity refers to the degree to which a study provides evidence that the independent variable is solely responsible for changes in the dependent variable. It assesses whether the observed effect is due to the experimental intervention or other factors, such as history or maturation, that may have affected the outcome. External validity refers to the generalizability of findings to other settings or populations, while test-retest reliability and split-half reliability are measures of consistency or stability of data over time.
