Question

The president of State University wants to forecast student enrollments for this academic year based on the following historical data: Year Enrollments 5 Years ago 15,000 4 Years ago 16,000 3 Years ago 18,000 2 Years ago 20,000 Last Year 21,000 What is the forecast for this year using four-year simple moving average

Answer 1

The forecast for this year using four-year simple moving average(SMA) is mathematically given as

Forecast for period of 4y=18750

Simple moving average(SMA)

Question Parameters:

5 Years ago 15,000

4 Years ago 16,000

3 Years ago 18,000

2 Years ago 20,000

Last Year 21,000

Generally the equation for the four years SMA  is mathematically given as

$SMA=\frac{four years digits}{number of years}$

Forecast for period of 4y =$\frac{16000 +18000 +20000 +21000 }{4}$

Forecast for period of 4y=18750

Therefore,the forecast for this year using four-year simple moving average(SMA) is

Forecast for period of 4y=18750
