The value of goodness-of-fit parameters helps determine whether it is reasonable that the data points are truly represented by a straight line.The linear correlation coefficient, r, is calculated from the sums used to find the intercept and slope, along with one additional sum from the data points (F1F1F1S1F1F1F10y²): 11ea6816_3f29_93b4_b611_9be767e9aef8_TB6242_00 The sign of the correlation coefficient is merely the same as the sign of the slope.
