When an experimented is designed, the researcher wants to study the effect the independent variable has on the dependent variable. However, if there's a third variable that can influence them, it can cause a spurious correlation.
The psychologist wanted to test the effects using the new computer program (independent variable) had in helping students learn math (dependent variable). But when she divided the group in two, separating them by gender, she introduced a third variable (confounding variable) that wasn't accounted for when designing the experiment and that can influence either variable. <u>Because of this, the internal validity of the study has been </u><u>lowered</u><u>.</u>

At first, I practiced piano for two hours each day, <em>with the result that</em> I progressed very rapidly. Every day for two years I raced home <em>when </em>school was done and practiced the piano with great enthusiasm. Then one day, something happened. I decided I liked baseball better than the piano. Though I can play the piano rather well <em>at the present time</em>, I do not practice as long nor as diligently as I once did.
