In statistics, the range of a data set is known as the difference between its largest and smallest values. All you have to do to find it is to arrange the set of numbers from smallest to largest and subtract the smallest value from the largest value. If you want to know how to quickly calculate the range of a data set, see Step 1 to get started.
Step
Step 1. Arrange a set of numbers from smallest to largest
Suppose your data set consists of the following numbers: {7, 8, 65, 8, 4, 7}. All you have to do is rewrite these numbers from smallest to largest to get a deeper understanding of the data you're working with. The arrangement would look like this: {4, 7, 7, 8, 8, 65}.
Step 2. Identify the smallest and largest numbers in the data set
In the data set you're working with, the smallest number is 4 and the largest number is 65. These numbers must be at the end (front or back) of the data set because you're rearranging the numbers from smallest to largest.
Step 3. Subtract the smallest number from the largest
Now, all you have to do is subtract the smallest number, which is 4, from the largest number, which is 65. 65-4 = 61.
Step 4. Write down your reach
"61" represents the range of this particular data set. Your task is done. If you want to find the range of a function, you have to follow a slightly more complicated process. However, that's all you need to do to calculate the range of a data set.
Tips
- Practice will make this calculation easy.
- If you don't know if your answer is correct, ask a math teacher or anyone who is very good at math.
- Use a calculator if needed.
