Explanation / Answer
a) The 3-week moving average is 385.3. (402 + 373 + 381) / 3 = 385.3 b) The weighted moving average is 391.2. 0.6*402 + 0.3*373 + 0.1*381 = 391.2 c) The exponentially smoothed forecast is calculated as such: Note: the previous answerer gave an incorrect calculation here. Pints Forecast for next period 360 360 389 365.8 = 0.2*389 + 0.8*360 410 374.6 = 0.2*410 + 0.8*365.8 381 375.9 = 0.2*381 + 0.8*374.6 372 375.1 = 0.2*372 + 0.8*375.9 402 380.5 = 0.2*402 + 0.8*375.1 The exponential forecast is 380.5 for the next period.
