Question

16. Use descriptive statistics on the following data of test scores:(Round to the hundredth if needed.)8,8,4,4,7,9,8,6,7,3,8,5MMean =Mode =Median=

Answer 1

For this question, first, we ordered the given data from lowest to highest:

`3,4,4,5,6,7,7,8,8,8,8,9`

Now, we use the formula for the mean of a data set:

`\text{Mean}=(3+4+4+5+6+7+7+8+8+8+8+9)/(12)=(77)/(12)\approx6.42`

From the ordered data we get that:

`\begin{gathered} \text{Mode}=8 \\ \text{Median}=(7+7)/(2)=7 \end{gathered}`
