📚 Topic Summary
The range of a data set is the difference between the largest and smallest values. It tells you how spread out the data is. To find the range, simply subtract the smallest number from the largest number in the set. For example, if your data set is 3, 5, 7, 2, and 9, the range would be 9 - 2 = 7.
Understanding the range helps in analyzing data and making comparisons. A larger range indicates greater variability, while a smaller range suggests the data points are closer together.
