## How to Find the Range from a Frequency Table

Finding the range from a frequency table is easy.

### Question

The frequency table below shows the test scores for a class of students.

What is the range of the test scores? # 1

Make sure the entries in the Score column are in numerical order. In our example, the entries are in numerical order.

# 2

Find the lowest entry in the Score column (with a Frequency greater than 0). In our example, the lowest entry is 5. The lowest test score is 5.

# 3

Find the highest entry in the Score column (with a Frequency greater than 0). In our example, the highest entry is 10. The highest test score is 10.

# 3

Subtract the lowest number (5) from the highest number (10).

10 − 5 = 5

The range of the test scores is 5. ## Slider
