The within sum of squares is the sum of the squared deviations from the mean. The mean of the time-trial data is 120.6 seconds. The squared deviations from the mean are:(115 - 120.6)^2 = 31.36(118 - 120.6)^2 = 6.76(122 - 120.6)^2 = 1.96(125 - 120.6)^2 = 18.49(127 - 120.6)^2 = 40.96(130 - 120.6)^2 = 84.64(132 - 120.6)^2 = 129.96(135 - 120.6)^2 = 202.56(138 - 120.6)^2 = 302.76(140 - 120.6)^2 = 361.00The within sum of squares is the sum of these squared deviations, which is 372.1.
