An electronics retailer was presented with in-store signage in two formats. Each branch of the store used the signage that matched its location. An analysis was performed to compare means on sales. Which type of variable do the sales represent?

A criterion variable is often used in the context of predictive models or assessments, indicating an outcome that is being measured. While sales could be seen as a criterion in some analyses, the more precise term in this scenario is 'dependent variable' since it specifically highlights how sales are affected by changes in the signage format.

An independent variable represents a factor that is manipulated or changed to observe its effect on another variable. In this case, the signage format is the independent variable, while sales are the outcome that changes based on this manipulation. Therefore, labeling sales as an independent variable is incorrect, as they are not the factor being controlled or altered.

While the term 'target variable' can be synonymous with 'dependent variable' in some contexts, it is not the standard terminology used in experimental design. In this analysis, identifying sales specifically as a dependent variable provides clearer insight into the relationship being examined.
