Question

A group of 7 students was asked, "How many hours did you watch television last week?" Here are their responses:17, 16, 4, 11, 13, 8,5Find the median and mean number of hours for these students.If necessary, round your answers to the nearest tenth.

Answer 1

Mean is given by:

$\begin{gathered} \operatorname{mean}=\frac{\text{Sum hours}}{\text{total students }}=\frac{17+16+4+11+13+8+5}{7} \\ =\frac{74}{7}=10.57 \end{gathered}$

Round to the nearest tenth = 10.6

Median

We order the data from smallest to largest:

4, 5, 8, 11, 13, 16, 17

Then we locate the middle data and this is the median.

The middle data is 11.

Answer:

Mean = 10.6

Median = 11
