Consider the data $: 2, 3, 9, 16, 9, 3, 9$. Since $16$ is the highest value in the observations,is it correct to say that it is the mode of the data? Give reason.
(B) $16$ is not the mode of the data. The mode of a given data is the observation with the highest frequency,not the observation with the highest value. In the given data,the frequency of $9$ is $3$,which is the highest frequency. Therefore,the mode of the data is $9$.
