Question

..pls.


find the mode.........​

Answer 1

Answer:

$\tt{Mode = l + (\frac{f_{1} - f_{0}}{2f_{1} - f_{0} - f_{2}})h}$

=> Here, values:

Highest frequency: 15

Modal class = 20 - 30

$\sf{f_{0}}$ = 10

$\sf{f_{1}}$ = 15

$\sf{f_{2}}$ = 8

h = 10

Mode = $\tt{20 + (\frac{15 - 10}{30 - 8 - 10})10}$

=> $\tt{20 + (\frac{5}{12})10}$

=> $\tt{\frac{120 + 25}{6}}$

=> $\tt{24.16}$
