Answer 2

SOLUTION

GIVEN

For a distribution the sum of lower and upper qualities is 50 and their difference is 10

TO DETERMINE

The coefficient of QD

EVALUATION

Here it is given that for a distribution the sum of lower and upper qualities is 50 and their difference is 10

Since the sum of lower and upper qualities is 50

Thus we get

$\displaystyle \sf{Q_3 + Q_1 = 50}$

Since their difference is 10

Thus we get

$\displaystyle \sf{Q_3 - Q_1 = 10}$

Hence the required quartile deviation

$\displaystyle \sf{ = \frac{Q_3 - Q_1}{Q_3 + Q_1} }$

$\displaystyle \sf{ = \frac{10}{50} }$

$\displaystyle \sf{ = \frac{1}{5} }$

$\displaystyle \sf{ = 0.2 }$
