- What does “Confidence-Interval Construction” mean?Confidence Intervals
- An estimate surrounded by a procedure-based margin of uncertainty.
- What important condition applies to confidence-interval construction?Confidence Intervals
- Check the procedure and multiplier before interpreting coverage.
- What does “Margin and Total Width” mean?Confidence Intervals
- The difference between an uncertainty margin and the interval’s complete span.
- What important condition applies to margin and total width?Confidence Intervals
- Do not confuse a one-sided margin with full interval width.
- What does “Standardized Test Statistics” mean?Hypotheses and P-Values
- A discrepancy from a null hypothesis measured in standard-error units.
- What important condition applies to standardized test statistics?Hypotheses and P-Values
- Specify the reference distribution and alternative before obtaining a p-value.
- What does “P-Values and Decisions” mean?Hypotheses and P-Values
- A tail-area measure of data incompatibility with a specified null model.
- What important condition applies to p-values and decisions?Hypotheses and P-Values
- A p-value is not P(H₀ is true).
- What does “Confidence-Level Interpretation” mean?Interpreting Conclusions
- The long-run coverage performance of an interval procedure.
- What important condition applies to confidence-level interpretation?Interpreting Conclusions
- Confidence refers to the repeated procedure, not a probability assigned to a fixed parameter.
- What does “Type I Errors and Multiple Testing” mean?Interpreting Conclusions
- False-positive errors considered across a collection of hypothesis tests.
- What important condition applies to type i errors and multiple testing?Interpreting Conclusions
- A nominal single-test error rate does not control an entire collection automatically.
