Question

What is the third quartile of the 8, 9, 12, 14, 15?

Answer 1

Answer:

14.5

Step-by-step explanation:

Case 2

Q3 =

$( \frac{3}{4} (n + 1 ) - \frac{1}{2} )th$

and

$( \frac{3}{4} (n + 1) + \frac{1}{2} )th$

$\frac{3}{4} (5 + 1) - \frac{1}{2} = 4th \: = 14$

$\frac{3}{4} (5 + 1) + \frac{1}{2} = 5th = 15$

$\frac{14 + 15}{2} = 14.5$
