WebStatistical Analysis. The Fisher Exact test is a test of significance that is used in the place of chi square test in 2 by 2 tables, especially in cases of small samples. Statistics … 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… sonny vero beach

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. sonny\u0027s wife in the godfather
