Step 1

The five-number summary is a descriptive statistic that provides information about a set of observations. It consists of the following statistics:

1. Minimum (Min) - the smallest observation

2. Maximum (Max) - the largest observation

3. Median $M$ - the middle term

4. First Quartile $Q_{1}$ - the middle term of values below the median

5. Third Quartile $Q_{3}$ - the middle term of values above the median

Step 2

Arrange the terms in ascending order.

$9, 9, 9, 9, 9, 9, 9$

Step 3

The minimum value is the smallest value in the arranged data set.

$9$

Step 4

The five most important sample values are sample minimum, sample maximum, median, lower quartile, and upper quartile.

$Min = 9$

$Max = 9$

$M = 9$

$Q_{1} = 9$

$Q_{3} = 9$
