"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. " - B value in statistics
