Find the mode of the following distribution:

Marks	$4$	$5$	$6$	$7$	$8$
No. of students	$6$	$7$	$10$	$8$	$3$

If $\alpha, \beta, \gamma$ are the mean deviations about the mean,median,and mode of the data $1, 2, 2, 3, 3, 3, 4, 6$ respectively,then

For a discrete series (where all values are not equal),what is the relationship between Mean Deviation $(M.D.)$,Mean $(Mean)$,and Standard Deviation $(S.D.)$?

Determine which of the following statements is true: $(1)$ The mode can be calculated using a histogram. $(2)$ The median is not independent of the change of scale. $(3)$ Variance is independent of the change of origin and scale.

If in a moderately asymmetrical distribution,the mode and mean of the data are $6 \lambda$ and $9 \lambda$ respectively,then the median is:

In a frequency distribution,if the mean and median are $21$ and $22$ respectively,then what is the approximate mode?
