Directions For Questions

As median divides an arranged series into two equal parts, in similar way quartile divides an arranged series in $$4$$ equal parts. For ungrouped frequency distribution formula of finding $$i$$th quartile$$={ Q }_{ 1 }={ \left\{ i,\left( \cfrac { N+1 }{ 4 } \right) \right\} }^{ th }\quad $$ term $$i=1,2,3$$
Quartile deviation: half of difference between upper quartile and lower quartile
Quartile deviation$$\left( Q.D \right) =\cfrac { 1 }{ 2 } \left( { Q }_{ 3 }-{ Q }_{ 1 } \right) $$
Coefficient of quartile deviation$$=\cfrac { { Q }_{ 3 }-{ Q }_{ 1 } }{ { Q }+-{ Q }_{ 1 } } $$
