WebJun 25, 2015 · The 2x5 table is not statistically significant with a chi-square test, (probably) because the outcomes for some conditions are very close together (e.g., the distribution of yes/no is very similar for ashamed and afraid). However, a pairwise comparison between only certain conditions (e.g., comparing neutral to sadness) does give significant ...

WebPROC POWER or the POWER2X2 macro computes the power of a test that compares proportions from two independent samples for a range of total sample sizes. The POWERRXC macro computes the power of the Pearson and likelihood ratio chi-square tests (provided in PROC FREQ) for a range of total sample sizes. WebChi-Square Calculator. The results are in!

WebOct 10, 2008 · Purpose: Perform an odds ratio chi-square test of a series of fourfold (2x2) tables. Description: Given two variables where each variable has exactly two possible outcomes (typically defined as success and failure), we define the odds ratio as: o = ( N11 / N12 )/ ( N21 / N22) = ( N11N 22)/ ( N12N21 ) where. WebFISHERTEST(R1, tails) = the p-value calculated by the Fisher Exact Test for a 2 × 2, 2 × 3, 2 × 4, 2 × 5, 2 × 6, 2 × 7, 2 × 8, 2 × 9, 3 × 3, 3 × 4 or 3 × 5 contingency table contained in R1.
