Weighted Average Calculator

A weighted average is an average where some numbers contribute more to the final result than others. Each number is assigned a "weight" that determines its importance.

The Process:

• Step 1: Multiply each number by its corresponding weight.
• Step 2: Sum all of the products from Step 1.
• Step 3: Sum all of the weights.
• Step 4: Divide the sum of the products (Step 2) by the sum of the weights (Step 3).

The formula is: Weighted Average = Σ(xᵢ * wᵢ) / Σwᵢ

Where xᵢ is each number and wᵢ is its weight.
