We have to represent the data on a scatter diagram, with length on the x-axis and width on the y-axis. Calculate the mean length x ¯ = 103 + 146 + 119 + 149 + 89 + 135 + 151 + 147 + 123 + 128 10 = 1290 10 = 129 Calculate the mean width y ¯ = 38 + 44 + 38 + 53 + 36 + 38 + 51 + 43 + 33 + 42 10 = 416 10 = 41 . 6 Plot the point M = ( 129 , 41 . 6 ) on the scatter diagram. Draw a line through M = ( 129 , 41 . 6 ) and through the middle of the other points. The points should be evenly distributed above and below the line. Thus, the required scatter diagram is
