To find the range of a set of data, you need to follow these steps:

Determine the minimum and maximum values: First, identify the lowest (minimum) and highest (maximum) values in the dataset.

Calculate the range: Subtract the minimum value from the maximum value. The result will give you the range.

Interpret the range: The range represents the spread or variation in the data. A larger range indicates a wider spread of values, while a smaller range indicates a more concentrated set of values.
By following these steps, you can easily find the range of a given set of data.
