Question
Given the following data on the number of pints of ice cream sold at a local ice cream store for a 10-period time frame:
| Period | Demand | 2 MA Forecast | Error square 2 MA= (De- Forecast)2 |
|---|---|---|---|
| 1 | 200 | ||
| 2 | 245 | ||
| 3 | 190 | (200+245)/2=222.5 | |
| 4 | 270 | (245+190)/2=217.5 | (270-217.5)2=2756.25 |
| 5 | 280 | (190+270)/2=230 | (280-230)2=2500 |
| 6 | 300 | (270+280)/2=275 | (300-275)2=625 |
| 7 | 320 | (280+300)/2=290 | (320-290)2=900 |
| 8 | 340 | (300+320)/2=310 | (340-310)2=900 |
| 9 | 320 | (320+340)/2=330 | (320-330)2=100 |
| 10 | 280 | (340+320)/2=330 | (280-330)2=2500 |
