AbolishedTables for statistical distributions--χ2-distribution
统计分布数值表 χ2分布
Application Summary AI generated
This standard provides tabulated critical values and probability points for the chi-squared (χ²) distribution, a fundamental tool in statistical hypothesis testing and confidence interval estimation. It is applied in fields such as quality control, reliability engineering, and experimental data analysis, where engineers and statisticians use the tables to determine significance thresholds for variance tests, goodness-of-fit tests, and independence tests in contingency tables. The standard ensures consistent and accurate reference values across Chinese industrial and scientific research contexts.
