Question

In a mathematics test given to 15 students the following marks are recorded :-
41,39,48,52,46,62,54,40,96,52,98,40,42,52,60 find the mean,median,mode of the above data.​

Answer 1

Dear mates here is your answer

$mean = \frac{sum \: ofall \: marks}{number \: of \: students}$

$mean = \frac{41 + 39 + 48 + 52 + 46 + 62 + 54 + 40 + 96 + 52 + 98 + 40 + 42 + 52 + 60}{15}$

$mean = mean = \frac{822}{15} = 54.8$

$median = \frac{n + 1}{2}th \: term = 8th \: term = 40$

$mode = highest \: frequency = 52$
