internal validity

Explanation:

The internal validity measures the degree to which the research is correct. This is done by determining the number of confounding variable.

A confounding variable is the variable that influences both the independent and dependent variable. Only the independent variable should influence the dependent variable.

When the confounding variables found in the research is low the internal validity of the research increases and if the confounding variables found in the research is high the internal validity of the research decreases.
