WebApr 13, 2024 · The Pearson chi-squared test revealed similar results when the score distribution was assessed for each sex by age group: There was a significant difference in the score distribution among age groups in females (Pearson chi 2 = 17.8256, p = 0.001), but not in males (Pearson chi 2 = 5.7630, p = 0.674). WebWe have implemented a Monte Carlo method for four 'chi-squared' test statistics, three of which involved combination of alleles, and evaluated their performance on a real data set. Combining rare alleles to avoid small expected cell counts, and considering each allele in turn against the rest, reduced the power to detect a genuine association ...
