 -   **alpha**: `number` in the interval `[0,1]` giving the significance level of the hypothesis test. Default: `0.05`.
 -   **alternative**: Either `two-sided`, `less` or `greater`. Indicates whether the alternative hypothesis is that the true ratio of variances is greater than one (`greater`), smaller than one (`less`), or that the variances are the same (`two-sided`). Default: `two-sided`.
--   **difference**: `number` denoting the difference in means under the null hypothesis. Default: `0`.
+-   **ratio**: positive `number` denoting the ratio of the two population variances under the null hypothesis. Default: `1`.
 
 By default, the hypothesis test is carried out at a significance level of `0.05`. To choose a different significance level, set the `alpha` option.
