24 6 Betsan surveyed a sample of 22 knitters. 12 of the knitters said they regularly attended knitting groups where they shared their hobby with others. 10 said they did not. The knitters were asked to rate how calming they found knitting on a scale from 0 ‘not at all’ to 100 ‘extremely’. Betsan decides to perform a Wilcoxon rank-sum test to find out whether knitters who attend knitting groups find knitting more calming, on average, than knitters who do not attend knitting groups. Betsan’s data are shown in Figure 8 along with a partial ranking of the ratings.
