What is the range of the following set of data?
10, 1, 4, 3, 4.4, 5.1, 1.1, 9?

Options

A. 12
B. 9
C. 12.4
D. 14.4

Answer

To find the range of the given set of data, we will follow these steps:

**Step 1: Identify the data set.**
The data set provided is:
10, 1, 4, 3, 4.4, 5.1, 1.1, 9.

**Step 2: Arrange the data in ascending order.**
We will sort the numbers from the smallest to the largest:
1, 1.1, 3, 4, 4.4, 5.1, 9, 10.

**Step 3: Identify the minimum and maximum values.**
From the arranged data, we can see:
- Minimum value = 1
- Maximum value = 10

**Step 4: Calculate the range.**
The range is calculated using the formula:
Range = Maximum value - Minimum value
So, substituting the values we found:
Range = 10 - 1 = 9.

**Final Answer:**
The range of the given set of data is 9.
