From the problem, we have the data :

Let's arrange the data from least to greatest.

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

That will be :

$\begin{gathered} \operatorname{mean}=(1+2+3+5+7+9+14+16+16)/(9) \\ \operatorname{mean}=8.1 \end{gathered}$

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 :

$\operatorname{median}=7$

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
