摘要:方差分析(Analysis of Variance缩写为ANOVA)是数理统计中常用的数据处理方法之一,在实际中也是工农业生产和科学研究中分析试验数据的一种有效工具,更是开展实验设计,参数设计和容差设计的数学基础。此文就单、双因素试验的方差分析结合事例详细的叙述了其在食品生产中的计算方法、对人力资源考评结果的信度进行了量化评价,并基于MATLAB进行建模,从而通过数据分析找出对事物有显著影响的因素和显著影响因素的最佳水平等.27866 毕业论文关键词:方差分析 ;自由度 ;显著差异 ;MATLAB
Application of variance analysis in practice
Abstract: ANOVA (analysis of variance abbreviation for ANOVA) is mathematical statistics in commonly used data processing methods, in practice is the industrial and agricultural production and scientific research analysis a valid tool to test data, it is to carry out the experimental design, the mathematical basis for parameter design and tolerance design. The single and double factor test of variance analysis with examples in detail describes the calculation method in the production of food, the human resources appraisal result reliability quantitatively, and modeling based on MATLAB, and through the data analysis to identify significant influence factors and significant factors that affect the optimal level of things.
