WebThere is a table of critical values for the Pearson's Product Moment Coefficient (PPMC) given in the text book. The degrees of freedom are n-2. Depending on the textbook you're using, you may be required to look up either n or the df in the table. Be sure to look at the table before you use it or you may get wrong critical values. WebHere is how it works. Each one-tailed critical value in Table 13.2 can again be interpreted as a pair of values: one positive and one negative. A t score below the lower critical value is in the lowest 5% of the distribution, and a t score above the upper critical value is in the highest 5% of the distribution. For 24 degrees of freedom, these ...
