## Summary of Fit

The **Summary of Fit** table contains summary
statistics including **Root MSE** and **R-Square**.
The **Root MSE** value is **0.6998** and is the square root of the
mean square error given in the **Analysis of Variance** table.
**Root MSE** is an estimate of in the preceding regression model.
The **R-Square** value is **0.2046**, which means that 20% of the
variation in **GPA** scores is explained by the fitted model.
The **Summary of Fit** table also contains
an adjusted R-square value, **Adj R-Sq**.
Because **Adj R-Sq** is adjusted for the number of
parameters in the model, it is more comparable over models
involving different numbers of parameters than **R-Square**.
