Testing The Significance Of The Correlation Coefficient Pdf. There is sufficient evidence to conclude that there is a significant linear relationship between X 1 and X 2 because the correlation coefficient is significantly different from zero. However we need to perform a significance test to decide whether based upon this sample there is any or no evidence to suggest that linear correlation is present in the population.
This is because rejecting the null-hypothesis as traditionally reported in social science papers ie. Mar 10 2021 Examining the scatter plot and testing the significance of the correlation coefficient helps us determine if it is appropriate to do this. Thus sxy 1 12 568254 95314355 Also sx 1 12 1060192 27096 sy 1 12 3396942 5312 334290 Hence r.

There is a linear relationship in the population that models the average value of y for varying values of x. Population correlation coefficient is denoted by ρ rho.
