Question

Quartile deviation for the data 1,3,4,5,6,6,10​

Answer 1

Answer:

Quartile Deviation = 1.5

Step-by-step explanation:

In ascending order, 1, 3, 4, 5, 6, 6, 10

Q1 = Value of [(n+1)/4]^th term

= Value of [(7+1)/4]^th term

= Value of 2nd term

= 3

Q3 = Value of [3(n+1)/4]^th term

= Value of [3(7+1)/4]^th term

= Value of 6th term

= 6

Quartile Deviation = ( Q3 - Q1 ) / 2

= (6 - 3) / 2

= 3/2 = 1.5

Hope it helps.
