The item mean for the three friendship scale items (Table I) was 1.472 with variance of .006. This mean was significantly higher (t287 = 25 .83,p < 0.001) than the mid-point of the scale (0 - Both Equally). The effect size was large, d = 1.53. Figure 5 shows that for the three friendship scale items, most of the respondents (approximately 70% to 75%) thought they were more friendly with their code review partners than their non-code review partners.
