Using Step-Deviatopn Method, find the mean (rounded off to nearest integer) of following frequency distribution:

Open in App

Solution

$A = 25, h = 10, N = 50$ and $\sum f i u i = 4$
$¯ x = A + h [\frac{1}{N} \sum f i u i]$
$\Rightarrow$ Mean $= 25 + 10 \times (4 / 50)$
$\Rightarrow$ Mean $= 25 + 0.8$
$∴$ Mean $= 25.8$
