Question 975199: I have a graph with two slopes and here is what is written: y=-0.02+-8.06E-4*x on one slop and y=-0.03+-1.13E-3*x. It is an SPSS graph and the legend says R Linear=0.093 and the other R Linear is 0.038. I cannot, for the life of me fathom how these Linear values equate to the slope formulae. Can you ????
Many thanks Answer by solver91311(24713) (Show Source):
R Linear is the correlation coefficient, and is measure of goodness of fit of your scatter plot data to the regression line defined by your linear functions. If your numbers are actually 0.093 and 0.038, then you have two lines that are extraordinarily poor fits for your data sets. , and the closer to 1 the better the fit.
