Answer
The $Modes$ of the data set are $\color{red}{2}$ and $\color{red}{16}$. Answers may vary.
Work Step by Step
$\text{Explaination}$
The $\text{Mode}$ is the value that appears the most often in a set of data.
$\text{For Example:}$
Assuming the Below $\text{Data Set}$:
$${\color{red}2, 5, 8, \color{red}{16}, \color{red}2, 22, 5, \color{red}{16}, \color{red}{2}, \color{red}{16}, 13, 9} $$
Hence The modes of the data set are $\color{red}{2}$ and $\color{red}{16}$ as they occur more than any other value in the given data set.
