statistics for quick numeric summaries

statistics is a handy module for basic numeric summaries. It saves you from rewriting common calculations like means and medians.

Why it is useful

import statistics

scores = [90, 70, 85, 95]
print(statistics.mean(scores))
print(statistics.median(scores))

For quick analysis, this is often all you need.

Good use cases

• summaries in scripts
• simple reports
• quick data checks
• lightweight numerical tooling

Rules of thumb

• Use statistics for basic descriptive summaries.
• Reach for it before writing custom mean or median code.
• Move to heavier tools only when the problem truly grows beyond it.
