Question

How do I find the Q1 and Q3?

0,0,1,2,2,3,4,4,4,4,5,6,6,7,7

Answer 1

Q1 = 2

Q3 = 6

Explanation:

Mathematically, we have

Q1 = (n + 1)/4 th term

where n is the number of terms

By the count, we have n as 15

Q1 = (15 + 1)/4

Q1 = 4th term

Looking at the arrangement, the 4th term is 2

For Q3

Q3 = 3(n + 1)/4 th term

n = 15

Q3 = 3 * 4 = 12th term

The 12th term is 6

So that is the 3rd quartile
