WebThe test statistic F test for equal variances is simply: F = Var (X) / Var (Y) Where F is distributed as df1 = len (X) - 1, df2 = len (Y) - 1 scipy.stats.f which you mentioned in your question has a CDF method. This means you can generate a p-value for the given statistic and test whether that p-value is greater than your chosen alpha level. Thus:
WebThe P -value is therefore the area under a tn - 1 = t14 curve to the left of -2.5 and to the right of the 2.5. It can be shown using statistical software that the P -value is 0.0127 + 0.0127, or 0.0254. The graph depicts this visually. Note that the P -value for a two-tailed test is always two times the P -value for either of the one-tailed tests. mistborn playing cardsWebTwo Tailed.
