Step-by-step explanation: Arrange ascending order, 17, 20, 22, 25, 27, 29, 35 Calculation of Q1 can be done as follows, Q1 = ¼ (7 + 1) =¼ (8) Q1=2 Term Q1 = 20 Calculation of Q3 can be done as follows, Q3=¾ (7 + 1) Q3= 3/4 (8) Q3= 24/4 Q3 = 6 Term Q3= 29 Q.D. = Q3 – Q1 / 2 Using the quartile deviation formula, we have (29 -20 ) / 2 =9/2 Q.D.=4.5 Reply
Step-by-step explanation:
Arrange ascending order,
17, 20, 22, 25, 27, 29, 35
Calculation of Q1 can be done as follows,
Q1 = ¼ (7 + 1)
=¼ (8)
Q1=2 Term
Q1 = 20
Calculation of Q3 can be done as follows,
Q3=¾ (7 + 1)
Q3= 3/4 (8)
Q3= 24/4
Q3 = 6 Term
Q3= 29
Q.D. = Q3 – Q1 / 2
Using the quartile deviation formula, we have (29 -20 ) / 2
=9/2
Q.D.=4.5
