Question

The following numbers are the sizes of shoes sold by a shop on a particular day.
6, 7, 8, 9, 10, 6, 7, 10, 7, 6, 7, 9, 7, 6.
Find the mode.

Answer 1

First we have to arrange the observations in order
6, 6, 6, 6, 7, 7, 7, 7, 7, 8, 9, 9, 10, 10 to make frequency distribution table

Size	6	7	8	9	10
Number of shoes sold	4	5	1	2	2

Here No. 7 occurred most frequently. i.e, 5 times.
∴ Mode (size of the shoes) of the given data is 7. This indicates the shoes of size No. ‘7’ is a fast selling item.
