The definition of R-squared (coefficient of determination) is fairly straight-forward; it is the percentage of the response variable variation that is explained by a linear model.
Hence, if R-squared is 0.216, then
21.6% of variation can be explained by the regression line.
78.4% of variation is unexplained and is due to other factors or to sampling error.
