Statistics How To

F Table

The F Table is used to look up F Statistics in hypothesis testing. While it’s more common to use technology like Excel or SPSS to run tests, the F Table can be useful for quickly looking up several different values at once.

F Tables.

f tableNote on reading the tables: DF2 is read DOWN the first column. DF1 is read ACROSS the top row. For example, if you wanted to find DF2 = 5, DF1 = 5 in the first table (α = .10), you would get 4.06042.

    You’d probably be able to do that with software, but I can’t honestly think of a reason why you’d want to run a test with a 99.999 significance level. At least, I’ve never come across anyone who’d want to run at that level before. I’m curious: why do you want that level? You’re going to end up with a huge confidence interval (one that probably isn’t helpful).

    How can I find the critical value of F at 11,11 (degree of freedom) at 0.025. I just found the numerator until 10?

    Hello, Taghreed,
    The table doesn’t have df1 of 11, so you’ll have to extrapolate between 10 and 12. Midway between 3.4296 and 3.5257 would be 3.47765.
