mystats-helper

A lightweight, pure-Python statistics helper library built for learning.

Installation

pip install mystats-helper-adamdockstader

In futurecoder / Pyodide

import micropip
await micropip.install("mystats-helper-adamdockstader")

Quick Start

import mystats_helper

data = [4, 8, 15, 16, 23, 42]

# Descriptive statistics
print(mystats_helper.mean(data))       # 18.0
print(mystats_helper.median(data))     # 15.5
print(mystats_helper.stdev(data))      # 13.28...
print(mystats_helper.describe(data))   # full summary dict

# Z-scores
print(mystats_helper.z_scores(data))

# Correlation & regression
x = [1, 2, 3, 4, 5]
y = [2, 4, 5, 4, 5]
print(mystats_helper.correlation(x, y))
slope, intercept = mystats_helper.linear_regression(x, y)
print(f"y = {slope:.2f}x + {intercept:.2f}")
