Why Sample Size Matters
Sample size is the number of valid observations supporting a historical statistic and determines how cautiously that statistic should be interpreted. Better investment decisions come from reading this evidence with related context rather than treating it as an isolated answer.

Key takeaways
- Sample size is the number of valid observations supporting a historical statistic and determines how cautiously that statistic should be interpreted.
- The concept should be read with related evidence and its stated limitations.
- Historical observations provide decision context; they do not predict or guarantee future results.
Common misinterpretations
- Treating one metric or state as a complete investment decision.
- Confusing a historical observation with a forecast or recommendation.
Historical observations are educational decision context. They do not predict future results or constitute investment advice.
