Suppose for a particular week, the forecasted sales were $4,000. The actual sales were $3,000.  What is the value of the mean absolute percentage error?

how to find percentage error

Given the forecast demand and actual demand for 10-feet fishing boats, compute the Mean Absolute Deviation (MAD) (answer correct to two decimal places).Year 1 2 3 4 5 6Forecast Demand (F) 78 75 83 84 88 85Actual Demand (A) 71 80 101 84 60 73

In a chemistry experiment, the volume of a liquid is measured three times as 55 mL, 57 mL, and 56 mL. If the actual volume is 56.5 mL, what is the percent error of the average measurement?Select one:a.0.0088b.0.0106c.0.0053d.0.0044

An advantage of measuring forecast error based on the mean absolute percentage error (MAPE) rather than the mean absolute deviation (MAD) is that MAPE does not depend on the scale of the data.Multiple ChoiceTrueFalse

(Enter only a number in the response box, not the units)    The yield of wool in a particular farm is modeled by a linear function  P(t)=90t+3,450P𝑡=90𝑡+3,450 , where  P(t)𝑃𝑡  is measured in kg and  t𝑡  in years.     What is the initial production?     P(0)=𝑃0=    kg.     What is the prediction for the production in 8 years? P(8)=𝑃8=     kg.         The value in 8 years is   P(8)=4,056𝑃8=4,056  kg.     What is the absolute error of this model at  t=8𝑡=8 ?  Absolute error =     kg.     What is the percentage error? Round the answer to one decimal place.               Percentage error =     %
