Weighted average

भारित औसत

In this Class 9 Mathematics topic from the Statistics chapter, students learn how to find an average when different values have different levels of importance, or weights. They understand the meaning of a weighted average, multiply each observation by its assigned weight, add the products, and divide by the total weight. The topic also helps students interpret results and apply the method to practical examples such as marks, prices, quantities, and survey data.
