In Kevin's experiment, "sales at a website" is the dependent variable as it is the outcome that is being measured and the variable that is expected to change in response to the different design styles. The design style is the independent variable as it is being manipulated by Kevin to see if it affects sales. The other options are not applicable in this situation.
