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.
