(C) Given data: $16, 22, 3, 14, 5, 10, 8, 6, 11, 4$. Arranging in ascending order: $3, 4, 5, 6, 8, 10, 11, 14, 16, 22$. Number of observations $n = 10$. Since $n$ is even,the median is the average of the $5^{	ext{th}}$ and $6^{	ext{th}}$ observations: $	ext{Median} = \frac{8 + 10}{2} = 9$. Mean deviation from the median is given by $\frac{1}{n} \sum |x_i - 	ext{Median}|$: $	ext{Mean Deviation} = \frac{|3-9| + |4-9| + |5-9| + |6-9| + |8-9| + |10-9| + |11-9| + |14-9| + |16-9| + |22-9|}{10}$ $= \frac{6 + 5 + 4 + 3 + 1 + 1 + 2 + 5 + 7 + 13}{10}$ $= \frac{47}{10} = 4.7$.

${x_i}$	$5$	$7$	$9$	$10$	$12$	$15$
${f_i}$	$8$	$6$	$2$	$2$	$2$	$6$

Class Interval	$0-4$	$4-8$	$8-12$	$12-16$
Frequency	$4$	$3$	$2$	$1$

The mean deviation from the median of the data $16, 22, 3, 14, 5, 10, 8, 6, 11, 4$ is
