MEDIAN:

First we have to arrange the numbers in ascending order.

AO: 21 31 35 38 39 42 46 46 46 59

median=\frac{n}{2} and \:  \frac{n}{2}+1 \:  \:  \:  \\ (if \: the \: number \: of \: observations \: are \: even) \\  \\ median =  \frac{n + 1}{2}  \\ (if \: the \: number \: of \: observations \: are \: odd)

As the number of observations (n)are 10. So we have to use first formula

 \frac{n}{2}  =  \frac{10}{2}  = 5 th \: term\\  \frac{n}{2}  + 1 = 5 \:  + 1 = 6th \: term

average of 5th and 6th term = median

 \frac{39 + 42}{2}  = 81 \div 2 = 40.5

Therefore, median = 40.5

_______________________________________

Mode:

mode= 46, as it's frequency is 3, and leftover numbers frequency is 1.

Frequency refers to the number of times an event or a value occurs.

Mean:

 \frac{sum \: of \: the \: observations}{number \: of \: observations}  = mean

 \frac{403}{10}  = 40.3

Therefore, mean= 40.3
