WebOnce we use these formulas to have our line, we can evaluate how well it fits our data using a metric called R-squared. In effect, R-squared measures how much of the variance can be explained by our fit line. R-squared = sum( (y_est - y_bar)^2) / sum( (y - y_bar)^2) This will evaluate to a number between 0 and 1, with 1 being a better fitting line.
