Students in math class throw darts at the wall to make a scatter plot. The dots appear to have positive correlation. The boys in the room calculate that the line of best fit should be y=3x+9y = 3 x + 9. The girls calculate that a best fit line should be at y=4x+5y = 4 x + 5
A coordinate plane was projected to identify the location of the points. The darts hit at (2,10), (3,19), (4,14), (5,23) and (6,30)
The class calculated the sum of the squares of the residuals to find out which group had the better line.
The sum of the squares of residuals for the boys line is:
The sum of the squares of residuals for the girls line is:
The: had the better line of best fit since the sum of the squares of their residuals was closer to:
