Test results

Number of samples	N = 1440
Wilcoxon rank-sum	W = 493560.000 z-score = -3.194 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 = -0.084
Mann-Whitney	U = 234000.000 z-score = -3.785 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 = -0.100
