Question

Compute Quartile co-efficient of skewness from the values given
as under-M= 37.6; Q1 = 29.2; and Q3 = 50.4​

Answer 1

Answer:

Quartile co-efficient of skewness = 0.0553 .

Step-by-step explanation:

Here we are given M = 37.6; $Q_1$ = 29.2; and $Q_3$ = 50.4​ where;

             $Q_1$ = First quartile

             M = $Q_2$ = Second quartile or Median

             $Q_3$ = Third quartile

Quartile co-efficient of skewness formula is given by ;

            ⇒  $\frac{Q_3 + Q_1 - 2*Q_2}{Q_3 + Q_1}$  =  $\frac{50.4 + 29.2 - 2*37.6}{50.4 + 29.2}$ = $\frac{11}{199}$ = 0.0553 .

Therefore, Quartile co-efficient of skewness = 0.0553 .
