The following correlation coefficients, (rvalues), andP-values were generated with StatCrunch.
Each of the columnsX1, X2, X3, X4, Y1, Y2, Y3,andY4have the same number of data items in them.
Correlation ofX1andY1=-0.998,P-value = 0.000
Correlation ofX2andY2=0.471,P-value = 0.169
Correlation ofX3andY3= 0.856,P-value = 0.002
Correlation ofX4andY4=-0.662,P-value = 0.037
