Results Hypothesis 1: Number of repository commits H0: Computer musicians and general software developers make the same number of commits. Ha: Computer musicians make less commits than general software developers. Figure 2 displays a side-by-side box plot of commit counts for the compiled computer music dataset and the random sample dataset. To properly display the results, the commit counts were transformed into the logarithmic domain.1 The median number of commits per computer music repository is 17, while the median for general software developers is 36 commits per repository. The Wilcoxon rank sum test reports a z-value of −7.332 and a p-value of 1.133e−13. The value of Cliff’s Delta effect size is small (−0.209±0.052 with 95% confidence). At α =0 .01 there is strong evidence to reject the null hypothesis and conclude that computer musicians make less commits than the general population of software developers. As several computer musicians noted during interviews, less commits may be made because of the community’s culture of sharing intellectual property or the inability of computer musicians to identify significant structural changes in code.
