The independent variable in this experiment is the presence or absence of music. The store is comparing sales on days when music is played versus days when it is not played, making the presence or absence of music the variable being manipulated. Factors such as the workers in the store, volume of sales, and variations in weather are not being intentionally manipulated and therefore cannot be considered as the independent variable.
