Answer :
Given:
Set is: 8,12,12,12,12,30
Find:
The measure of the typical value
Explanation:
[tex]\begin{gathered} \text{ Mean=}\frac{\text{ Sum of observations}}{Total\text{ number of observations}} \\ \text{ } \\ \text{ Mean=}\frac{8+12+12+12+12+30}{6} \\ \\ \text{ Mean=}\frac{86}{6} \\ \\ =14.33 \end{gathered}[/tex]so the value of mean is 14.33
For Median.
For even terms is:
[tex]\text{ Median=}\frac{(\frac{n}{2})^{th\text{ }}\text{ term+\lparen}\frac{n}{2}+1)^{th\text{ }}\text{ term}}{2}[/tex]So the median is:
[tex]\begin{gathered} \text{ Median=}\frac{12+12}{2} \\ \\ =12 \end{gathered}[/tex]So mean and median good measure of typical value.
