find the Mean Median Mode of the given table by $D E V I A T I O N$ METHOD with Each step for Mean Median Mode.

Open in App

Solution

Mean $(¯ x) = A + \frac{\sum f_{i} d_{i}}{\sum f_{i}} = 35 + \frac{0}{30} = 35$

Median = Average of $15^{t h}, 16^{t h}$ observations $(∵ n = 30)$

$= \frac{34 + 35}{2}$

$= 34.5$

Mode = most occurring observation $= 34$
