itna bara ni hta q.d

misbah apka Q1 or Q3 kia aya hai? 

mera Q1 = 2304 hai 

Q3 = 300000 hai...

So 300000-2304/2 = 148848 aya hai... correct me if i am wrong. thanks 

oho kya o gya ittni bari values o data me ni hein apki kasy aa gain.. 

any way, Q1= 96 , Q2 = 1200 

coz Q1= value of (n+1/2)th iem , and ,

Q3= value of 3 (n+1/4)th item of the data as well..

Q1 or Q3 ase nikalta hai... mene exact ase hi nikala hai.. aap dekhy kia is tarha hai ? 

ye solution mene notes se nikala hai..

Position of Q1 = (n+1)/4 = (10+1)/4 = 2.75
So Q1 = 2nd value + 0.75 × (3rd value – 2nd value)
= 8 + 0.75 × (9 - 8)
= 8 + 0.75 x 1
= 8.75


Position of Q3 = 3 × (10 + 1) /4 = 3 × (2.75) = 8.25
So Q3 = 8th value + 0.25(9th value – 8th value)
= 20 + 0.25 × (22 –20)
= 20.50

n= 15 hy.. 10 nhi.. count karen ap pahly

here n means the ttotle number of observations dear..

oho mene apko sample solution dikhaya hai k mene is tarha kara hai... ap apna solution dekho k apne same is tarha kara hai? ye humare question ka solution nahi hai mene sample dikhaya hai apko...
