Example1. Calculate Quintile-4 from the following data
`85,96,76,108,85,80,100,85,70,95`
Solution:
Arranging Observations in the ascending order, We get :
`70,76,80,85,85,85,95,96,100,108`
Here, `n=10`
`"Quintile"_4 = ((4(n+1))/5)^(th)` value of the observation
`=((4*11)/5)^(th)` value of the observation
`=(8.8)^(th)` value of the observation
`=8^(th)` observation `+0.8[9^(th)-8^(th)]`
`=96+0.8[100-96]`
`=96+0.8(4)`
`=96+3.2`
`=99.2`
