What do the moving average calculations on the number of customers each day tell Chloe? What do the other statistics tell her? How can this data help her make decisions about daily operations?
What will be an ideal response?
The moving averages are helpful in spotting trends over a period of time by smoothing out any fluctuations that may occur during each consecutive interval. Moving average data can be used to create charts to show whether the value is trending upward or downward. Chloe can see which days of the month generate higher sales, and along with the other statistics like mean, median, and mode, she can better plan for daily supplies and staffing needs.
