  1. The statistical significance of difference in the mean of the normalized coefficient of dissimilarity (Ω) and DaliLite Z score in terms of Student's two-sided t-test at 95% confidence interval. The small p-values from the t-test indicate a significant difference in the mean value of the two scores for the respective shared SCOP level. The p-values for the F-test reported at 95% confidence interval indicate that the two-sided t-test is valid based on the assumption of equality of the two sample variances. Mean Norm = normalised mean.
