13 maj 2022 · Knowing r and n (the sample size), we can infer whether ρ is significantly different from 0. Null hypothesis (H 0): ρ = 0; Alternative hypothesis (H a): ρ ≠ 0; To test the hypotheses, you can either use software like R or Stata or you can follow the three steps below. Step 1: Calculate the t value
