Test results

Number of samples	N = 1200
Wilcoxon rank-sum	W = 336900.000 z-score = -3.898 Asymptotic significance (2-tailed) p < 0.001 Based on a significance level of 0.01, there is a statistically siginificant difference between 'Java' and 'Python'. Effect size r = -0.113
Mann-Whitney	U = 156600.000 z-score = -4.867 Asymptotic significance (2-tailed) p < 0.001 Based on a significance level of 0.01, there is a statistically siginificant difference between 'Java' and 'Python'. Effect size r = -0.140
