Explore the DMAIC improve phase in the Six Sigma black belt course, covering simple and multiple regression, data transformation, full factorial experiments and fractional factorial experiments, and exam preparation tools.
Apply the Box-Cox transformation to normalize non-normal dependent variables in multiple regression, and identify the optimal lambda from the normality plot.
Review designed experiments concepts, including randomization and replication, randomized designs and blocking, factors and controllable variables, predictors, and their interactions.
Explore full factorial experiments through a quiz discussion that covers design definitions, levels and factors, trial counts, orthogonality, yates analysis, anova p-values, and center-point interpretation.
Explore fractional factorial designs through a quiz, clarifying that a fraction equals fewer tests than full factorial design and that both map the design space with two-level factors.
