Confounding variable

A confounding variable is a variable which has an unintentional effect on the dependent variable. When carrying out experiments we attempt to control extraneous variables, however there is always the possibility that one of these variables is not controlled and if this affects the dependent variable in a systematic way, we call this a confounding variable.
