NettetThis gives us 21/45 or about 46.7% of the data points above the line of best fit – not exactly half, but pretty close. Some data points may lie precisely on the line of best fit. However, most data will fall above or below the line of best fit unless the data has a very strong correlation (that is, a high value of R, close to 1 or -1).
