F-distribution - Wikipedia

WebIn probability theory and statistics, the F-distribution or F-ratio, also known as Snedecor's F distribution or the Fisher–Snedecor distribution (after Ronald Fisher and George W. Snedecor) is a continuous probability distribution that arises frequently as the null distribution of a test statistic, most notably in the analysis of variance (ANOVA) … WebThe t-table indicates that the critical values for our test are -2.086 and +2.086. Use both the positive and negative values for a two-sided test. Your results are statistically significant if your t-value is less than the negative value or greater than the positive value. The graph below illustrates these results. One-sided t-test WebConsider the following competing hypotheses and relevant summary statistics: (You may find it useful to reference the appropriate table: chi-square table or F table) H 0: σ21/σ22σ12/σ22 ≤ 1.
