A shoe shop is planning next month's order from its supplier. Which average of the sizes sold last month tells the manager which single size to stock most heavily?

Erklärung

The size sold to the most customers is the one the counting average reports, so stocking that size in the largest quantity matches the largest group of buyers. The mean of the sizes is the closest rival but can come out at a figure such as 7.4, which no supplier stocks, so it names no size the shop could order at all.
