Question

Find , , , and . Round the mean to the nearest tenth. 9, 3, 2, 1, 14, 16, 16, 7, 5

Answer 1

From the problem, we have the data :

`9,3,2,1,14,16,16,7,5`

Let's arrange the data from least to greatest.

`1,2,3,5,7,9,14,16,16`

Mean is the average of the data or the sum divided by the number of data.

That will be :

Median is the middle term of the data when arranged from least to greatest. Since we have a total of 9 data, the middle term will be the 5th data.

That will be :

Mode is the data with the most number of repetition.

Since 16 appears twice.

That will be :

`\text{Mode}=16`

Range is the difference between the highest value and the smallest value.

That will be :

`\begin{gathered} \text{Range}=16-1 \\ \text{Range}=15 \end{gathered}`

ANSWERS :

mean = 8.1

median = 7

mode = 16

range = 15
