Question

Suppose you will perform a test to determine whether there is sufficient evidence to support a claim of a linear correlation between two variables. Find the critical values of r given the number of pairs of data n and the significance level α. n = 11, α = 0.05

Answer 1

To find the critical value of r given the number of pairs of data and the significance level, you need to check the value into a table of critical values for Pearson Correlation.

Then for n=11, degrees of freedom (df) are n-2=9 and a significance level α=0.05, the critical value for r is =0.602
