Common comparison error
Confidence interval stated to two decimals is not precise evidence unless sample size, uncertainty, and Observed win rate support it.
GlossaryStrategy & risk
Confidence interval
A range expressing uncertainty around an estimated win rate or other statistic. It helps prevent a small sample from being presented as a precise result.
Practical use
How to verify Confidence interval
Read Confidence interval together with Sample size, Observed win rate, Break-even win rate. The comparison must preserve the exact rule, value, state, and evidence described below.
A neutral example
Six months develop the rules for Confidence interval; three later months remain frozen for evaluation. No parameter changes after Sample size results are opened. Confidence interval is distinguished here by one decisive fact: a 58 percent rate from 40 outcomes has wider uncertainty than the same estimate from 4,000 outcomes.
Evidence path
Where to verify Confidence interval
Use the source that governs the exact contract, account, entity, or platform state. A general definition cannot replace current broker terms.
