Respond to this... Provide your assessment of the information provided. The weighted average model for computer sales showed more deviation and error as k was increased meaning that the most reliable data was the most recent data in shorter periods compared to recent data over longer periods. This fluctuation was due to inconsistent sales which made the data much more volatile. What is the best Weighted Average Model? Why? The best weighted average model was the 2 period because it has the lowest deviation, absolute error and squared error. As k increases all these metrics increase which makes the forecast less reliable and therefore the first 2 period model is the best. What is the best Exponential Smoothing Model? Why? The best exponential smoothing model is both the .6 and .7 smoothing constant models. Both of these constant models have a mean absolute percentage error of 27.09%. Mape forecasting is better with a lower value and both these constants have the lowest values of all the forecasts. Feel free to highlight any challenges or learnings you experienced with Excel. I don't like how the format does not also get copied when I copy and paste the data
