Web2 Aug 2024 · A correlation coefficient is a bivariate statistic when it summarizes the relationship between two variables, and it’s a multivariate statistic when you have more than two variables. If your correlation coefficient is based on sample data, you’ll need an inferential statistic if you want to generalize your results to the population. WebEntering table B at 15 – 2 = 13 degrees of freedom we find that at t = 5.72, P < 0.001 so the correlation coefficient may be regarded as highly significant. Thus (as could be seen immediately from the scatter plot) we have a very strong correlation between dead space and height which is most unlikely to have arisen by chance.
