In mathematics, a factor is any number that multiplies with another to produce a product. Assigning weights to factors allows you to emphasize the importance of one component over another. Weighted factors are commonly used in educational grading systems, ensuring that each assignment contributes proportionally to a student’s final score.

Step 1 – Identify the Factors and Their Weights

Begin by listing each component and its assigned weight. For example, a student scored 90 % on a test that accounts for 60 % of the final grade, and 80 % on a second test worth 40 %.

Step 2 – Multiply Each Factor by Its Weight

Calculate the weighted contribution of each component. In the example, 90 % × 60 % = 54 % and 80 % × 40 % = 32 %.

Step 3 – Sum the Weighted Contributions

Add the results from Step 2. 54 % + 32 % = 86 %. This 86 % is the student’s overall weighted score.
