Suppose participants complete an experiment where ads are presented subliminally during a task (e.g., Pepsi ads are flashed at a very fast rate during movie ads). Participants are then given a recognition test for images of the ads, where two images are presented, and participants must choose which one of the two was presented earlier. Both men and women (18 of each gender) participate in the study, and the researcher predicts that recognition accuracy (0 100%) will differ based on gender. Which best describes this scenario?
