Question

In the data set shown below, what is the value of the quartiles?

{4.3, 4.5, 4.7, 5, 5.5, 5.7, 5.9, 6, 6.1}
A. Q1 = 4.6; Q2 = 5.5; Q3 = 5.95
B. Q1 = 4.7; Q2 = 5.5; Q3 = 6
C. Q1 = 4.7; Q2 = 5.5; Q3 = 5.9
D. Q1 = 4.6; Q2 = 5.5; Q3 = 5.92

Answer 1

A.Q1 = 4.6;Q2 = 5.5;Q3 = 5.95

Explanation:

I hope this helps

Answer 2

• A. Q1 = 4.6; Q2 = 5.5; Q3 = 5.95

Explanation:

Q2 is the median of the data set:

• Q2 = 5.5

Q1 is the median of lower half:

• Q1 = (4.5 + 4.7)/2 = 4.6

Q3 is the median of upper half:

• Q3 = (5.9 + 6)/2 = 5.95

Correct choice is A
