Fisher's test calculator
WebThe Fishers LSD test is basically a set of individual t tests. The only difference is that rather than compute the pooled SD from only the two groups being compared, it computes the pooled SD from all the groups. If all groups are sampled from populations with the same SD, using all the data to compute the pooled SD gives a more accurate value ... WebThe Fisher's Exact Test. Fisher's exact test is particularly appropriate when dealing with small samples. This section only covers test on a 2 by 2 table. That is, there are two …

Web1. It seems unwise to do Fisher's exact test with ordinal data - you throw away so much of the information. It's possible to do exact tests by using some statistic that incorporates ordinal information. Expected cell counts less than 5 shouldn't be a problem - expecteds that are fairly similar can go down a fair bit smaller and still get an an ...
Web$\begingroup$ Is there a way to calculate p-values from odds ratio?In fisher.test I don't understand the alternative hypothesis argument. It says alternative hypothesis must be one of "two.sided", "greater" or "less" and that the alternative for a one-sided test is based on the odds ratio, so alternative = "greater" is a test of the odds ratio being bigger than or? what … highlights to cover gray on dark hairWebContingency tables are used to analyze counts of subjects to determine if there is association between two factors.
