F Test Statistika. Unsurprisingly the f test can assess the equality of variances. σ 1 2 σ 2 2.
For example you can use f statistics and f tests to test the overall significance for a regression model to compare the fits of different models to test specific. σ 1 2 σ 2 2 alternate hypothesis h a. Df 1 n 1 1 11 1 10 df 2 n 2 1 21 1 20.
The p value is a probability while the f ratio is a test statistic calculated as.
The p value is a probability while the f ratio is a test statistic calculated as. In the case of graph a you are looking at the residuals of the data points and the overall sample mean. σ 1 2 σ 2 2 alternate hypothesis h a. σ 1 2 σ 2 2.
