Question

Find the 1st and 3rd quartile of
the set of numbers.
17, 1, 14, 7, 12, 15
​

Answer 1

Ok so first you have to put the numbers in order of least to greatest:

1, 7, 12, 14, 15, 17

Next you find the median of the numbers or middle:

1, 7, 12 | 14, 15, 17

Then you find the median of both halves:

1 {7} 12 | 14 {15} 17

So the first quartile is 7 and the third quartile is 15
