Internal validity asserts that variations in the dependent variable originate from variations in the independent variable(s) – not from other confounding factors. In experiments, internal validity is also based on how much control has been attained in the research while collecting data. Internal Validity. Internal validity refers to a study’s ability to determine if a causal relationship exists between one or more independent variables and one or more dependent variables. In other words, can we be reasonably sure that the change (or lack of change) was caused by the treatment?

The illustration below shows the relationship in respect to validity. Internal Validity: Definition • Internal validity refers to the extent to which we can accurately state that the independent variable produced the observed effect. • If – effect on dependant variable only due to variation in the independent variable(s) • then – internal validity achieved Internal validity is the degree in which one can deduce or include that a causal relationship exists between two variables. It is information derived from evidence and reasoning rather than from explicit statement according to (Answers to Study Questions Ch. 8 – University of South Alabama.,” n.d.).
