数据的统计处理和解释 正态分布均值和方差检验的功效
Application Summary AI generated
This standard provides statistical methods for calculating the power of hypothesis tests concerning the means and variances of normal distributions. It is applied in quality control, experimental design, and industrial production settings where engineers need to determine the sample size required to detect a specified effect size or to evaluate the reliability of test results. The standard is particularly relevant for manufacturing and scientific research involving measurement data that follows a normal distribution.
