Chi Square Test With High Sample Size And Unbalanced Data Cross Validated from stats.stackexchange.com
The Minimum Detectable Effect is the smallest effect that will be detected 1-β of the time. Its the EXPECTED count that needs to be 5 per cell. For small sample sizes use Fishers exact test because the chi2 test sampling statistics has only approximately the chi2 distribution and this approximation is problematic for small sample sizes.
For each value of alpha we can calculate two sample sizes.
The sample size required for a chi-square test of independence with w 3 alpha 01 and power 8 for a 22 contingency table is 130. Its the EXPECTED count that needs to be 5 per cell.
