Distribution of P-values for 10,000 two sample t tests for Lognormal data.
<p>Means were compared between two groups of 10 observations from a Lognormal distribution.</p
P-values for chi-squared and Fisher’s exact tests for large groups of varying size.
<p>Chi-squared and Fisher’s exact test, both two-sided and one-sided, were calculated for10,000 comparisons in samples of size 2,000, both group and outcome having probability 0.5 of being 0 and 0.5 of being 1.</p
Distribution of P-values for chi-squared tests and Fisher’s exact tests for two by two tables.
<p>Chi-squared and Fisher’s exact test, both two-sided and one-sided, were calculated for the comparison of two samples of size 10 with a binary outcome variable with probability 0.5 of being 0 and 0.5 of being 1.</p
Distribution of P-values for 10,000 two sample t tests for Normal data.
<p>Means were compared between two groups of 10 observations from a Standard Normal distribution.</p
P-values for chi-squared and Fisher’s exact tests for large samples with fixed size groups.
<p>Chi-squared and Fisher’s exact test, both two-sided and one-sided, were calculated for10,000 comparisons of two samples of size 1,000 with a binary outcome variable with probability 0.5 of being 0 and 0.5 of being 1.</p
