PROBLEM VI. The number of items sold over a six-month period and the forecarts by two different techniques (F1 and F ) are given below. Calculate MAD and MSE for both techniques. Based on the MAD value, which one would you prefe? (22) The value of Mean Absoluie Deviation (MAD) for the first technique (yielding F1 ) is: (23) The value of Mean Absolute Deviation For the sccond technique (yielding F2) is: (b) 47.83 (b) 53.33 (c) 52.59 (d) 52.81 (e) none of the above (24) For the first technique (yielaing FI), the value of s=MSE is: (a) 61.64 (b) 58.92 (c) 71.27 (d) 88.47 (makk the closed answe) (25) For the socond technique (yielding F2), the value of s=MSE is: (n) 66.33 (b) 49.37 (c) 51.62 (d) 73.29 (mark the clones annwer)
