The explained variation in y refers to the portion of the total variation in the dependent variable (y) that is explained by the regression model. This is represented by the distance between the mean of y (the average value of y) and the predicted values of y (the values on the regression or best-fit line), not the distance between the observed values and the predicted values or any other points.
