Join the Statistics Division on Tuesday, January 16th at 8:00PM Eastern for a webinar to be given by Adam Pintar
Analysis of Variance, or ANOVA, is a fundamental tool in Statistics and Quality. It plays a critical role in analyzing data from designed experiments and forms the foundation of gauge R&R studies. This presentation focuses on the basics. The one-way ANOVA table is introduced, and a graphical interpretation of its components is provided. The situation is then complicated by adding a second factor leading to the two-way ANOVA table. Hypothesis tests for the importance of each factor are explained in terms of comparing the predictive ability of two models. Interactions are discussed.
NIST Standard Reference Materials will form the context of the discussion, to which ANOVA models naturally apply. However, the data presented in the examples will be simulated for pedagogical purposes.
The session will be planned to last 30 to 40 min to leave time for questions. Software for performing the requisite calculations will not be covered.
