How to Calculate the Arithmetic Mean - Formula and Method
The arithmetic mean is calculated by dividing the sum of all values by their count. In other words, you add all grades together and divide by the number of grades. Our calculator uses exactly this formula:
Example: if your grades are 5, 4, 3, and 6, the calculation is: (5 + 4 + 3 + 6) / 4 = 4.50. The calculator automatically rounds the result to two decimal places for precision.
If your grades carry different weights (e.g., an exam counts more than a quiz), use the weighted average calculator, which factors in grade weights for a more accurate result.
What is the Arithmetic Mean? Definition and School Context
The arithmetic mean is a fundamental statistical measure that represents the central tendency of a data set. In education, it reflects a student's overall academic performance across all subjects. It is widely used for report card averages, honours qualifications, and scholarship eligibility.
In the Polish education system, the arithmetic mean is the default method for calculating final grades - unless the school applies a weighted grading system. If your school uses the Librus register with plus and minus grades, try our Librus grade calculator for automatic conversion.
Grading Scale in Polish Schools
Poland uses a six-point grading scale (1-6). The table below shows each grade alongside its meaning and requirements. Understanding these thresholds helps you interpret your calculated average and its implications for your report card.
| Grade | Result | Weight |
|---|---|---|
| 6 | Excellent | above requirements |
| 5 | Very good | full requirements |
| 4 | Good | above basics |
| 3 | Satisfactory | minimum curriculum |
| 2 | Acceptable | gaps, at risk |
| 1 | Unsatisfactory | does not meet requirements |

Honours Stripe Average and Plus/Minus Grades
Many students use the grade average calculator to check whether they qualify for the Honours Stripe (czerwony pasek). In most Polish schools, this requires a minimum average of 4.75 and exemplary or very good conduct. Enter your grades in the form above to see your current standing.
This calculator accepts decimal values (e.g., 4.5 instead of 4+). If you prefer to enter grades in Librus format with plus and minus notation (5-, 4+), use our Librus calculator for automatic conversion.
Frequently Asked Questions
The arithmetic mean is the sum of all grades divided by their count - every grade carries equal importance. A weighted average assigns different weights to each grade, so a major exam (with a higher weight) impacts your final result more than a pop quiz.
Add up all your final grades from every subject, then divide by the number of subjects. You can do this manually or use our calculator - simply enter the grades and click Calculate for an instant result.
This tool calculates only the arithmetic mean (without weights). If your school uses a weighted grading system, switch to our weighted average calculator.
Most Polish schools award the Honours Stripe for an average of at least 4.75 and exemplary or very good conduct. Some schools and high schools may set a higher threshold, such as 5.0.
In this calculator, enter grades as decimal numbers: type 4.5 for 4+ and 3.75 for 4-. If you prefer Librus-style notation, use our Librus calculator which converts plus/minus automatically.
There is no limit. Click "Add grade" to add more fields. The calculator handles anything from a few grades for one subject to a full list of report card averages.
