Question

find the mean median and mof of following data Cl=100-150,150-200,200-250,250-300,300-350 and fi=4,5,12,2,2 respectively

Answer 1

$mean= \frac{sum \: of \: the \: observation}{no \: ofhe \: observation} \\ \\ = \frac{50 + 50 + 50 + 50 + 50}{5} \: \\ = \frac{250}{5} = 50$

$arranging \: in \: assending \: order \\ \: meadian = \frac{n + 1}{2} \: \: \: \: \\ \frac{50 + 2}{2} = 26 \: ans$
