WebMay 13, 2024 · Step 2: Find the critical value of t. You can find the critical value of t (t*) in a t table. To use the table, you need to know three things: The degrees of freedom (df): For Pearson correlation tests, the formula is df = n – 2. Significance level (α): By convention, the significance level is usually .05.
In inferential statistics, you estimate a parameter of a population by calculating a statistic of a sample. The number of independent pieces of information used to calculate the statistic is called the degrees of freedom. The degrees of freedom of a statistic depend on the sample size: 1.
