Example: Linear Regression on a TI-84 Calculator. Suppose we are interested in …Critical Values for the correlation coefficient r. Consult the table for the critical value of v = (n - 2) degrees of freedom, where n = number of paired observations.For example, with n = 28, v = 28 - 2 = 26, and the critical value is 0.374 at a = 0.05 significance level. Thus, an observed r = 0.31 in a sample of n=28 observations is not significantly different from random.The regression equation will also be stored to Y1.
