Formula Used
1) Cumulative Running Average
Running Averagen = (x1 + x2 + ... + xn) / n
2) Weighted Running Average
Weighted Averagen = (Σ(xi × wi)) / (Σwi)
3) Moving Average
Moving Average = (Sum of values in the selected window) / (Number of values in that window)
4) Weighted Moving Average
Weighted Moving Average = (Σ(window value × window weight)) / (Σ window weights)
Use cumulative mode for long-term progress. Use moving mode to smooth short-term fluctuations and highlight recent performance changes.

Frequently Asked Questions
1. What does a running average show?
A running average shows how the overall average changes whenever a new value is added. It helps students and teachers track progress across quizzes, assignments, and tests over time.
2. When should I use a moving average instead?
Use a moving average when you want to focus on recent performance only. It smooths short-term variation and makes newer trends easier to interpret than a full cumulative average.
3. Can I enter weighted scores?
Yes. Enable weighted averaging and provide one weight for each value. This is useful when exams, projects, or major assignments count more than quizzes or practice tasks.
4. What window size should I choose?
A smaller window reacts faster to change. A larger window gives smoother results. For classroom performance, many users start with three to five recent scores.
5. Does the calculator support decimals?
Yes. You can enter decimal values and choose up to eight decimal places in the final output. This helps when working with percentages, scaled marks, or research data.
6. Why does my latest average differ from the simple average?
If you use moving averages or weights, the latest displayed average may not match the simple arithmetic mean of all values. The chosen method changes the result intentionally.
7. Can this calculator help with grade forecasting?
It helps you monitor trends and estimate direction, but it does not replace a full grading model. Use it alongside your syllabus, grading weights, and remaining assessments.
8. What file formats can I export?
You can export the results table as CSV for spreadsheet work and as PDF for printing, reporting, or sharing with students, teachers, and academic advisors.
