分散分析（ANOVA）

Analysis of Variance (ANOVA) is a statistical method used to determine if there are significant differences between the means of three or more independent groups. In the context of product design and innovation, ANOVA helps researchers evaluate the impact of different design variables or production methods on product performance or consumer preferences. By identifying which factors contribute to variability in outcomes, ANOVA aids in making informed decisions to optimize product development and enhance overall quality.
