T-test BIOLOGY FOR LIFE. How to Calculate the Score for a T Distribution. When you look at the t-distribution tables, youвЂ™ll see that you need to know the вЂњdf.вЂќThis means вЂњdegrees of freedomвЂќ and is just the sample size minus one. Step 1: Subtract one from your sample size. This will be your degrees of freedom. Step 2: Look up the df in the left hand side of the t-distribution table., For a correlation study, the degrees of freedom is equal to 2 less than the number of subjects you had. If you collected data from 27 pairs, the degrees of freedom would be 25. Use the critical value table to find the intersection of alpha .05 (see the columns) and 25 degrees of freedom (see rows)..
