STEP 1

1. The data set contains nine data points: $59, 1, 1, 4, 4, 28, 20, 5, 9$ .
2. The range is calculated as the difference between the maximum and minimum values in the data set.

STEP 2

1. Identify the maximum and minimum values in the data set.
2. Calculate the range.

STEP 3

List the data points:
$59, 1, 1, 4, 4, 28, 20, 5, 9$

STEP 4

Identify the maximum value:
$\text{Maximum} = 59$
Identify the minimum value:
$\text{Minimum} = 1$

STEP 5

Calculate the range using the formula:
$\text{Range} = \text{Maximum} - \text{Minimum}$
$\text{Range} = 59 - 1$
$\text{Range} = 58$
The range is:
$\boxed{58}$
