The confidence interval for the ratio of two variances requires the use of the probability distribution known as the F-distribution. |
The F distribution is an asymmetric distribution that has a minimum value of 0, but no maximum value. The curve reaches a peak not far to the right of. |
The distribution of all possible values of the f statistic is called an F distribution, with v1 = n1 - 1 and v2 = n2 - 1 degrees of freedom. |
The F statistic is a ratio (a fraction). There are two sets of degrees of freedom; one for the numerator and one for the denominator. |
The F distribution is a right-skewed distribution used commonly in another statistical test called an Analysis of Variance (ANOVA). |
The F distribution is used in many cases for the critical regions for hypothesis tests and in determining confidence intervals. Two common examples are the ... |
