Question

Where is average useful?

Answer 1

Answer:

Averages are a useful way of getting an overall picture. You work out one figure to represent all the data. She adds them up to get the total and divides by the number of days. We are thinking about pints of milk which have to be bought in whole numbers, so the average amount that they use is 3 pints a day.
