The amount spent on food and drink by 20 customers is shown below What is the modal amount spent and the median?

40 25 8 36 18 15 24 27 43 9 12 19 22 34 31 20 26 19 17 28

Mode = 19.

Median = 23.

Step-by-step explanation:

Arrange in ascending order:

8 9 12 15 17 18 19 19 20 22 24 25 26 27 28 31 34 36 40 43

The modal amount is the one which occurs most, which is 19.

The median is the middle value of the 20 amounts.

As there is an even number of amounts the median is the mean of the 2 middle numbers:

Median = (22 + 24) / 2

= 23.
