Answer 1

Hi dear......


grouped data Use the following calculations to find the median for a grouped frequency distribution.

$take \: the \: \frac{n}{2} th \: term \\ \frac{ \frac{n}{2} + cf }{f} \times h \\ where \: n = total\: of \: all \: frequency \\ cf = cumiliative \: frequency \\ f = frequency \\ and \: h = class \: interval$
