WebApr 2, 2024 · ρ = population correlation coefficient (unknown) r = sample correlation coefficient (known; calculated from sample data) The hypothesis test lets us decide whether the value of the population correlation coefficient ρ is "close to zero" or "significantly different from zero". WebA correlation coefficient is a value that tells you how closely two data series are related. A commonly used example is the weight and height of 10 people in a group. If we calculate the correlation coefficient for the height and weight data for these people, we will get a value between -1 and 1.
