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.

Essentially, an R-Squared value of 0.9 would indicate that 90% of the variance of the dependent variable being studied is explained by the variance of the independent variable.
