Question

What are the minimum, first quartile, 20 70 13 15 23 17 40 51

Answer 1

Minimum 13

First quartile 16

Explanation:

Rewrite the sample 20 70 13 15 23 17 40 51 in ascending order:

13 15 17 20 23 40 51 70

The minimum is 13.

The median is the middle number

13 15 17 20 23 40 51 70

The middle number between 20 and 23 is

`(20+23)/(2)=21.5`

Consider first half of the sample

13 15 17 20

The first quartile is the middle number of this part. The middle number of

13 15 17 20

is

`(15+17)/(2)=16`
