Mean square error is calculated by dividing the squared sum of actual and forecast value by the number of forecast value. It is defined as : MSE=A-F2n Mean absolute deviation is calculated by dividing the modules difference for actual and forecast value by the number of forecast value. MAD=∑A-Fn Mean absolute percentage error is calculated by dividing the sum of absolute error and actual value multiplied by 100 with the number of forecast value. MAPE=∑A-FA×100nGiven : The customer satisfaction data as : Month Satisfaction Score (A) Forecast (F) A-F A-F A-F2 A-FA A-FA×100 1 88.6 83.9 4.7 4.7 22.09 0.053047404 5.304740406 2 87.9 86.3 1.6 1.6 2.56 0.018202503 1.820250284 3 89.6 88.6 1 1 1 0.011160714 1.116071429 4 92.7 89.2 3.5 3.5 12.25 0.037756203 3.77562028 5 91.4 90.3 1.1 1.1 1.21 0.012035011 1.203501094 Total 11.9 39.11 0.132201835 13.22018349 From the table value, MSE : MSE=A-F2n=39.115=7.822 MAD : MAD=∑A-Fn=11.95=2.380 MAPE : MAPE=∑A-FA×100n=13.220183495=2.644 Hence, MSE=7.822MAD=2.380MAPE=2.644
