How to find the range of a set of data

Sure, here are the steps to find the range of a set of data:

1. Organize the data set: Arrange the data set in ascending order (from smallest to largest).

2. Identify the smallest and largest numbers: Once the data set is organized, the smallest number will be the first one and the largest number will be the last one.

3. Subtract the smallest number from the largest number: The range is calculated by subtracting the smallest number from the largest number in the data set.

For example, if your data set is {4, 6, 9, 3, 7}, first organize it to {3, 4, 6, 7, 9}. Then subtract the smallest number (3) from the largest number (9), which gives you a range of 6.
