64.4 -497.7
73 -1279.2
29.1 553.6
346.3 934.6


What is the correlation coefficient with the outlier?
rw = 

What is the correlation coefficient without the outlier?
rwo = 

Would inclusion of the outlier change the evidence for or against a significant linear correlation?
  • Yes. Including the outlier changes the evidence regarding a linear correlation.
  • No. Including the outlier does not change the evidence regarding a linear correlation.
