How well this equation describes the data (the 'fit'), is expressed as a correlation coefficient, R2 (R-squared). The closer R2 is to 1.00, the better the fit.

Interpreting R-squared

Once you run a regression, one of the first bits of output is an R-squared. No matter how complicated your regression model, you will almost always interpret the R2. 

That's because the R2 tells you a really important piece of information: How much of the variance (the individual differences) in your outcome variable are being explained by your predictors. 

Even if you have a statistically significant predictor (a slope that's significantly different from zero), you might still only be explaining a very small proportion of the variance in your outcome. 

R2 can be interpreted like this: If R2 = .31, that means that 31% of the variance in your outcome has been explained by your predictor(s).
