WebOct 12, 2024 · The F test statistic is 4.3871 and the corresponding p-value is 0.03825. Since this p-value is less than .05, we would reject the null hypothesis. This means we have sufficient evidence to say that the two population variances are not equal. Method 2: F-Test in R. The following code shows how to perform an F-test using the first method: WebThe statistic Fmax is calculated as the ratio of the largest and smallest variances of the (k) groups each containing (n) observations: Clear up mathematic problem Our team is …

WebLevene’s test works very simply: a larger variance means that -on average- the data values are “further away” from their mean. The figure below illustrates this: watch the histograms become “wider” as the variances increase. We therefore compute the absolute differences between all scores and their (group) means.
