Weighted average Calculation
Sum of product of weight (wi) and data number (xi) which is then divided by sum of weights is called weighted average calculation:
Note: ∑ is the symbol for sum.
Example:
You can find the weighted average of equal class grades 40,40,50,50,50,60. As these grades are of equal weightage so we can calculate their weighted average by taking simple average or by counting how many times each grade appear.
Step 1: Add up all values
40+40+50+50+50+60 = 290
Step 2: Count how many values
There are 6 values.
Step 3: Divide total by count
290 / 6=48.333
✅ So the average = 48.33 (approximately).
