Quizplus · Accepted Answer

Varying the amount of advertising exposure and then measuring changes in sales illustrates the concept of causality because it allows researchers to determine if changes in one variable (advertising exposure) directly caused changes in another variable (sales). The other options, showing an ad and asking about reactions, and giving a sample product and asking about satisfaction, do not necessarily establish a causal relationship between the variables being measured.
