Values in the table are the critical values of r, r c, for the given confidence level. Critical values of r may be computed from:... Table of critical values for Pearson's r: Compare your obtained correlation coefficient against the critical values in the table, taking into account your degrees of freedom (d.f.= the number of pairs of scores, minus 2). Example: suppose I had correlated the age and

- Click on the name of a calculator to download it. T Distribution Table. This spreadsheet contains calculators that determine a critical t-value for a given alpha and that determine a probability for a given t-value.
- Use the critical value table to find the intersection of alpha .05 (see the columns) and 25 degrees of freedom (see rows). The value found at the intersection (.381) is the minimum correlation coefficient r that you would need to confidently state 95 times out of a hundred that the relationship you found with your 27 subjects exists in the population from which they were drawn.
- By "critical value", I assume you mean the critical values for either a t-test or a z-text. Excel has several formulas related to t-tests, but the formulas for finding the critical values are either T.INV for a one-tailed test, or T.INV.2T for a two-tailed test.
