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=

Respuesta :

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

[tex]3,4,4,5,6,7,7,8,8,8,8,9[/tex]

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

[tex]\text{Mean}=\frac{3+4+4+5+6+7+7+8+8+8+8+9}{12}=\frac{77}{12}\approx6.42[/tex]

From the ordered data we get that:

[tex]\begin{gathered} \text{Mode}=8 \\ \text{Median}=\frac{7+7}{2}=7 \end{gathered}[/tex]
