What does R Squared mean in SPSS?

R-Square – R-Square is the proportion of variance in the dependent variable (science) which can be predicted from the independent variables (math, female, socst and read). This value indicates that 48.9% of the variance in science scores can be predicted from the variables math, female, socst and read.

What do casewise diagnostics tell us?

It is worth also collecting the Casewise Diagnostics. These will tell us which cases have residuals that are three or more standard deviations away from the mean. As before we should also request the Histogram and Normal Probability Plot (P-P plot) in order to check that our residuals are normally distributed.
