Explanation:

Confounding variable is a term in research methodology that describes a form of an additional variable that the researcher did not prepare for.

In other words, it is considered as an external influence that alters the effect of a dependent and independent variable. For example, the weather could be considered as a confounding variable that may change the effect of the experiment design.
