Question

Calculate q1,q2 and q3 from the following data. 15,21,26,30,40,45,50,54,60,65,70​

Answer 1

Given:

Individual Series (x) = 15,21,26,30,40,45,50,54,60,65,70​

To Find:

Q1 = ?

Q2 = ?

Q3 = ?

Solution:

Q1 = Size of $(\frac{N+1}{4} )^{th}$ item

Q1 = Size of $(\frac{11+1}{4} )^{th}$ item

Q1 = Size of $(\frac{12}{4} )^{th}$ item

Q1 = Size of $3^{rd}$ item = 26

Q2 = Size of $2(\frac{N+1}{4} )^{th}$ item

Q2 = Size of $2(\frac{11+1}{4} )^{th}$ item

Q2 = Size of $2(3)^{rd}$ item

Q2 = Size of $6^{th}$ item = 45

Q3 = Size of $3(\frac{N+1}{4} )^{th}$ item

Q3 = Size of $3(\frac{11+1}{4} )^{th}$ item

Q3 = Size of $3(3)^{rd}$ item

Q3 = Size of $9^{th}$ item = 60
