Question

A group of 5 students was asked, "How many hours did you watch television last week?" Here are their responses.

5, 5, 5, 4, 17
Find the mean number of hours for these students.
If necessary, round your answer to the nearest tenth.

Answer 1

7.2 Hours

Explanation:

To find the mean which is also known as the average of a set of data, you first have to add all the numbers then divide the sum by the amount of data values. (I remember this by saying the mean teacher averages your grade.)

First, you need to add the numbers. 5+5+5+4+17= 36

Secondly, you need to divide the sum of all the data by the amount of data there is. In this case, there are 5 pieces of data.

Lastly, you divide 36/5

Your final answer should be 7.2

You can check your work by doing 7.2 times 5 which equals 36.
