Given that the 3-month moving average for any period is equivalent to the May forecast, hence. the forecast for May will be 72 complaints
The average of numbers is also known as their mean. The average of numbers is the ratio of the sum of numbers to the sample size. Mathematically;
Average = Sum of data/Sample size
In order to calculate the forecast for May according to the given table, we will need to get the average complaint for the last 3 months.
Mean = Sum of complaints in February, March, and April/3
February complaint = 45 complaints
March complain = 81 complaints
April = 90 complaints
Find the forecast for May
Mean (Average) = (45+81+90)/3
Mean (Average) = 216/3
Forecast for May = 72 complaints
Since the 3-month moving average for any period is equivalent to the May forecast, hence. the forecast for May will be 72 complaints
