F means in statistics

WebStatistical location covers mean, median, and mode, where mean may not always be the same as the median or mode for skewed distributions. The mean of a probability distribution is the long-run average value of a random variable with that distribution. Generalized means include power mean and f-mean. The power mean is an abstraction of quadratic ... WebThe F statistic is a ratio of 2 different measure of variance for the data. If the null hypothesis is true then these are both estimates of the same thing and the ratio will be around 1. The numerator is computed by measuring the variance of the means and if the true means of the groups are identical then this is a function of the overall ...
