  The F-Distribution is a probability distribution that models the sampling distribution of F under the empty model (the null hypothesis that there is no effect of the explanatory variable); this theoretical distribution takes into account both model ...

• sample distribution

  When sampled data—units that were selected and measured—are shown in such a way where we can see patterns of variation (such as shape, center, and spread); sample distributions can be seen in visualizations such as histograms, boxplots, etc. but also ...
