Step $1$ of $5$: Determine the three$-$period moving average for the next time period. If necessary, round

your answer to one decimal place.

Answer $1$ Point

Step $3$ of $5$: Determine the three$-$period weighted moving average for the next time period with weights

of $3($most recent$),2($second recent$),$ and $1($oldest time period$).$ If necessary, round your answer to one

decimal place.

Answer $1$ Point

Consider the following data:

Step $5$ of $5$: Based on the MAD scores, which forecast is best?

Answer $1$ Point

Three$-$period moving average, because the MAD score is lowest.

Three$-$period moving average, because the MAD score is highest.

Three$-$period weighted moving average, because the MAD score is highest.

Three$-$period weighted moving average, because the MAD score is lowest.

Consider the following data:

Step $2$ of $5$: What are the MAD, MSE and MAPE scores for the three$-$period moving average? Round any

intermediate calculations, if necessary, to no less than six decimal places, and round your final answer to

one decimal place.

Answer $1$ Point

MSE $=$ubrace$(ubrace{)}_{\text{M}\text{A}\text{P}\text{E}}=$

Consider the following data:

Step $4$ of $5$: What are the MAD, MSE and MAPE scores for the three$-$period weighted moving average

forecast? Round any intermediate calculations, if necessary, to no less than six decimal places, and round

your final answer to one decimal place.

Answer $1$ Point
