📚 Topic Summary
The range of a dataset is the difference between its largest and smallest values. It provides a simple measure of variability, indicating how spread out the data points are. To find the range, simply subtract the smallest value from the largest value. This concept is used in many real-world scenarios, like calculating the variation in daily temperatures or analyzing the spread of salaries in a company. Understanding the range helps to quickly assess the dispersion of data.
