Quiz Score Average Calculator
Average comparable quiz scores with equal weighting, or supply a matching list of non-negative weights.
How to use Quiz Score Average Calculator
1. Enter Scores, Weights (optional) using the same scoring scale or point-total model. Leave weights blank for equal weighting. 2. Keep earned points and scores non-negative; enter a target between 0 and 100 where requested. 3. Select Calculate or press Enter to see average score. 4. Select Select Copy result to copy the answer or Reset to clear the form.
Why use this tool?
Average quiz results expressed on one common scale and give optional relative weights to different quizzes.
How the calculation works
Without weights, average = sum of scores ÷ number of scores. With weights, average = sum(score × weight) ÷ sum(weights). Weights must match the scores and have a positive total. Quiz weighting, retakes, dropped results and penalties vary. This calculator uses the scores and totals you supply; it does not choose or apply a course’s quiz policy. Percentages, point gaps and differences use up to two decimal places; averages use up to three. Smaller nonzero results use six significant digits in scientific notation. Browser floating-point rounding applies. Numeric input and result magnitudes must not exceed 9,007,199,254,740,991. Score and weight lists support up to 20,000 entries.
Example
Scores = 6,8,10, Weights (optional) = 1,1,1 gives “8”.
Practical tip
For assessments with different maxima, convert each score to the same percentage scale before averaging. To pool raw points, weight percentages by each assessment’s available points.
Frequently asked questions
Can I average raw marks from different maxima?
Only if you deliberately want that raw-score average. To compare performance fairly on a common scale, convert to percentages; the choice between equal and point-based weighting must match your grading policy.
What grading rules are assumed?
Quiz weighting, retakes, dropped results and penalties vary. This calculator uses the scores and totals you supply; it does not choose or apply a course’s quiz policy.
Are extra credit and fractional points supported?
Non-negative fractional points are accepted. Supplied earned points or scores above the ordinary maximum can represent existing extra credit. Targets are limited to 0–100%; future target-score planning assumes at most the stated available points. The tool does not determine your grading policy.
