How to calculate the weighted average of grades?
To calculate the weighted average of grades, you need the values of individual grades and their corresponding weights. In high school, this is the weight of your tests (exam=3, quiz=1). At university, these are your credit points (ECTS). Use our calculator or follow these steps:
- 1. Make sure you have the values and corresponding weights for each grade.
- 2. Multiply each grade by its weight.
- 3. Add all the obtained products together.
- 4. Add all weights together.
- 5. Divide the sum of products by the sum of weights.
The formula for weighted average of grades
Weighted average = (grade1 × weight1 + grade2 × weight2 + ... + gradeN × weightN) / (weight1 + weight2 + ... + weightN). Where grade1, grade2 ... gradeN are the individual grades, weight1, weight2 ... weightN are the corresponding weights, and N is the number of grades and weights.
How to calculate the arithmetic average?
To calculate the arithmetic average, add all values and divide by the number of values. Follow these steps:
- 1. Add all grade values together.
- 2. Count the number of grades.
- 3. Divide the sum of values by the number of grades.
The formula for arithmetic average
Grade average = (grade1 + grade2 + grade3 + ... + gradeN) / N. Where grade1, grade2, grade3 ... gradeN are the individual grades and N is the number of grades.
What does Wikipedia say about weighted average?
The weighted average generalizes the arithmetic mean and provides a characterization of a statistical dataset when the values in the dataset have different importance or weights. It is especially used when calculating the overall arithmetic mean of a dataset consisting of multiple subsets. To calculate the weighted average, both the values we want to average and their weights are needed.
