What value represents the difference between the highest and lowest numbers in a dataset?

The value that represents the difference between the highest and lowest numbers in a dataset is known as the range. To calculate the range, you subtract the smallest value in the dataset from the largest value. This measure gives you an understanding of the spread or variability of the numbers within the dataset.

For example, if you have a dataset of numbers like 3, 7, and 15, the highest number is 15 and the lowest number is 3. The range would be calculated as 15 - 3, which equals 12. This tells you that there is a total spread of 12 units among the values.

In contrast, the mean refers to the average of the dataset, calculated by summing all values and dividing by the total number of values. The median is the middle value when all numbers are arranged in order, while the mode is the number that appears most frequently in the dataset. Therefore, these concepts are related to different aspects of a dataset and do not represent the difference between the highest and lowest values like the range does.
