During the late 1980s and the early 1990s the Pepsi Challenge was in full swing. During the challenge, participants were asked to taste cola from both Coke and Pepsi. Once they had tasted both drinks, the participants were asked to report which was better tasting. The results indicated that participants found Pepsi products to be better tasting. This is an example of what type of research design?

A within-subject design

Explanation:

The Pepsi Challenge is an example of a within-subject design because is an experiment that exposes all participants to every option of the independent variable, meaning the one that's controlled by the people conducting the research. The opposite would be a between-subjects study design, in which there are different people testing each option, so each participant would only test either Pepsi or Cocke.
