Judge whether a sample represents the population and spot the selection, survivorship, and response biases that invalidate conclusions. Use when drawing conclusions from data that is a sample of something larger, which is almost always.

From the source SKILL.md

Nearly all data is a sample of a larger population, and the conclusion is only as good as the sample is representative. Biased sampling is the silent killer of analysis: the math is flawless, the p-value is tiny, and the answer is wrong because the data was drawn wrong. Spotting it is a core guardrail.

What this skill does

Sampling And Bias is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/sampling-and-bias/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when drawing conclusions from data that is a sample of something larger, which is almost always.
