Why Do We Need Averages?
Imagine you're comparing the heights of students in two different classes. Class A has heights: 150cm, 155cm, 160cm, 165cm, 170cm. Class B has heights: 140cm, 150cm, 160cm, 170cm, 180cm. Which class is taller on average? Without calculating averages, it's hard to tell at a glance!
Averages help us summarize data with a single representative value, making comparisons easier and patterns clearer.
