Question 15

A health psychologist investigated food craving intensity in two groups of participants. Participants in Group X had completed a 6-week mindfulness-based intuitive eating program, while participants in Group Y had completed a 6-week standard portion-control support group. Each participant completed a standardized food craving questionnaire (generating a score from 10 to 80, where higher scores indicate stronger cravings). The psychologist calculated measures of central tendency for each group, as shown in Table 3 below.

Table 3: Measures of central tendency for Group X and Group Y food craving scores
