Statistics module for MicroPython, based on statistics module for Python 3 (>= 3.4) :
- documentation of Python 3 statistics module
- PEP 0450 about Python 3 statistics module
- source code of Python 3 statistics module
All Python 3 statistics functions are implemented on MicroPython version, with the same syntax :
| Function | Description |
|---|---|
| mean() | Arithmetic mean (“average”) of data |
| harmonic_mean() | Harmonic mean of data |
| median() | Median (middle value) of data |
| median_low() | Low median of data |
| median_high() | High median of data |
| median_grouped() | Median, or 50th percentile, of grouped data |
| mode() | Mode (most common value) of discrete data |
| pstdev() | Population standard deviation of data |
| pvariance() | Population variance of data |
| stdev() | Sample standard deviation of data |
| variance() | Sample variance of data |
The MicroPython version of statistics module has some limitations :
- less precision on mean due to the lack of fraction numbers and 'float.as_integer_ratio()' on MicroPython;
- Fraction (from fraction module) and Decimal (from decimal module) are not accepted numbers because the fraction and decimal modules are not implemented on MicroPython;
- no error messages;
- no documentation and examples for each function inside the module.
Many MicroPython modules are optimised to save RAM memory because many microcontrollers only have tens of KBytes.
