Question

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

Answer 1

Answer:

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.
