WebFisher’s Exact Test is a statistical test used to determine if the proportions of categories in two group variables significantly differ from each other. To use this test, you should have two group variables with two or more options and you should have fewer than 10 values per cell. See more below. Fisher’s Exact Test is also called the ... Fisher's method combines extreme value probabilities from each test, commonly known as "p-values", into one test statistic (X ) using the formula where pi is the p-value for the i hypothesis test. When the p-values tend to be small, the test statistic X will be large, which suggests that the null hypotheses are not true for every test. When all the null hypotheses are true, and the pi (or their corresponding test statistics) are inde… can diabetics eat dried beans

Kurtosis is a measure of the tailedness of a distribution. Tailedness is how often outliers occur. Excess kurtosis is the tailedness of a distribution relative to a normal distribution. Distributions with medium kurtosis (medium tails) are mesokurtic. Distributions with low kurtosis (thin tails) are platykurtic.
