## How to Compute a Weighted Mean ### Formula **Weighted Mean = (v1*w1 + v2*w2 + ... + vn*wn) / (w1 + w2 + ... + wn)** Each value is multiplied by its weight before summing. The result is then divided by the sum of all weights. This is useful when some observations matter more than others, such as course grades with different credit hours.

हल किया गया उदाहरण

A student scores 85 (3 credits), 90 (4 credits), and 78 (2 credits). What is the weighted GPA?

  1. 01Weighted sum = 85*3 + 90*4 + 78*2 = 255 + 360 + 156 = 771
  2. 02Total weight = 3 + 4 + 2 = 9
  3. 03Weighted mean = 771 / 9 = 85.6667
