Distributions

Questions

What is Distributions?

A distribution describes the full spread of possible outcomes: where values cluster, how wide they range, and how often extremes appear. Two situations with the same average can have very different shapes, and the shape is often what matters for decisions.

How do you use Distributions?

To use it, ask about the range, not just the typical case. Plan your time, money and designs around the realistic spread, including the bad days. Gather several observations before judging, and remember that past patterns may not cover every future surprise.

When does Distributions matter?

Distributions is one of the 68 mental models for evidence, the situations where you ask: Is this really true? Within that, it belongs to “Reading the numbers”, alongside Base Rate Fallacy, Bayes’ Theorem and Central Limit Theorem.

What is an example of Distributions?
