Answer:
Moving average MSE =1.235
Exponential smoothing MSE =3.555
forecast for next month =(83+84+83)/3=83.33
Step-by-step explanation:
a)
Select your answer - Plot (iii)
What type of pattern exists in the data? -Horizontal Pattern
b)
for Moving Average MSE =1.235
for Exponential smoothing MSE =3.555
Moving Average is better
c)
forecast for next month =(83+84+83)/3=83.33
It can be deduced from the graph that the type of pattern that exists in the data is a horizontal pattern.
How to interpret the graph
From the complete question, when comparing the three-month moving average forecast with an exponential smoothing forecast, the forecast for moving average is 1.235 while that of exponential smoothing is 3.555. Therefore, moving average is better.
In conclusion, the forecast for next month will be:
= (83 + 84 + 83)/3
= 83.33
