Question

You're setting sales goals for next month. You base your goals on previous average sales. The actual sales for the same month for the last 4 years have been 24 units, 30 units, 23 units, and 27 units. What is the average number of units you can expect to sell next month?

Answer 1

To find the previous average sales, add the units sold in the same month in each of the last 4 years: 24 + 30 + 23 + 27 = 104. Then divide the sum by the number of different values, which in this case is 4. 104/4 = 26. Since sales goals are based on the previous average sales, you should expect to sell 26 units next month.
