Connecting the Dots…

The one that appears most

A shop sold seven pairs of shoes. Sizes: 5, 6, 6, 7, 6, 8, 7. Which size should the shop buy most of?

Loading lab…

Figure 1 — size 6 has the tallest pile, three pairs.

The shop should buy most of size 6.

Count how often each value appears. The value that appears most often is the mode.

Size 6 appears three times. The mode is 6.

Two piles can tie, with the same height. Runs in each of five overs: 4, 4, 5, 6, 6. The modes are 4 and 6.

Sometimes nothing repeats. Tickets numbered 3, 5, 8, 9 have no mode.
