Difference of R^2 Value in Multivariate & Line of Fit (Graph Builder)

[#1]

I am using same dataset for two ways to get the r^2 value but they have different results. Whats the difference between the two?

1. Analyze > Multi Variate

2. Graph same parameters in X & Y and get the R^2 of line of fit

I assume you are comparing R^2 from graph builder to Correlations table in Multivariate platform?

Basic Analysis > Bivariate Analysis > Statistical Details for the Bivariate Platform > Statistical ... (I assume this is same as graph builder)

Hi @PieFerret952 : If you have a regression model, Y vs x, you will see R^2.  R is the correlation coefficient you see when you use the multivariate platform. So, R^2 = correlation^2.  Or, correlation = +/-sqrt(R^2).
