Class statistics in seconds
After every test, teachers need a clear picture: what's the average, how many passed, are grades close together or spread out? Paste the grades and this tool answers all of it — entirely in your browser, so no names or grades are sent anywhere.
How to use it
- Copy the grade column (or name and grade columns) from Excel or your mark book and paste it. Decimal commas or points both work.
- Choose the maximum grade (20, 10 or 100) and the pass mark.
- Click “Analyse results” to see statistics, distribution and ranking.
- Copy the summary for a report, or download a CSV for Excel.
What each value means
| Value | What it tells you |
|---|---|
| Mean | The average grade; strongly affected by extreme values. |
| Median | Half the class is above, half below; more robust than the mean with outliers. |
| Standard deviation | How spread out the grades are: small means a homogeneous class, large means clear gaps that may call for support groups. |
| Pass rate | Share of students at or above the pass mark. |
Using the results
A decent mean with a large standard deviation suggests two levels in the class — a support session for the weaker group may help. Grades clustered low may mean the test was harder than intended or part of the lesson needs re-teaching. The distribution chart shows this at a glance.
