F table two tail

WebFor a left-tailed test 1 - \(\alpha\) is the alpha level. However, if it is a two-tailed test then the significance level is given by \(\alpha\) / 2. The F table is used to find the critical value at the required alpha level. The intersection of the x column and the y row in the f table will give the f test critical value. WebJun 28, 2024 · so the alpha value in t-table with respect to one-tail should be 0.05 for 95% confidence. but here in t-table we see that the value corresponding to one-tail is 0.025. Why? As far as I know for two tail we will split alpha into two tails and then we will have 0.025 on each tail. hypothesis-testing.
