Internal validity examines if the planning, carrying out, and analysis of the study yield objective solutions to the research objectives.
What is internal validity?Internal validity is defined as the level of assurance that the causal link you are evaluating is not affected by additional variables or circumstances. As a result of ignoring confounding factors, high internal validity enables the researcher to select one explanation over another with sufficient confidence.
When three conditions are met the "cause" precedes the "effect" in time, the "cause" and the "effect" tend to occur together, and a valid causal inference may be drawn. There aren't any logical alternatives to the observed covariation.
Thus, internal validity tests whether the study's planning, execution, and analysis provide unbiased answers to the research objectives.
