Your instructors, your parents, and your feelings of stress during finals week all tell you that cramming is a bad way to prepare for exams. Participants in Kornell’s (2009) research study received two sets of flash cards with vocabulary questions that they studied multiple times. One stack of flash cards was studied with a long amount of time between consecutive presentations of the same question. The other stack of flash cards was crammed—participants studied those questions with only a short amount of time between consecutive presentations. After studying the flash cards, participants were tested for the number of correctly remembered answers from all flash cards. The following represent data like those observed by Kornell (2009):

Create a frequency table for each of the two conditions. Does there appear to be a difference between the two groups?
