Lesson 11: ANCOVA II

Printer-friendly versionPrinter-friendly version
Key Learning Goals for this Lesson:
  • Learning how to use ANCOVA to analyze experiments with factor levels that are quantitative (numerical).
  • Fitting polynomial models for the quantitative factor
  • Testing hypotheses for treatment effects on polynomial coefficients. 

In Lesson 11 we are going to extend work with ANCOVA to look at quantitative factor levels.  We will revisit an older method in ANOVA, orthogonal polynomial coding, with modern statistical software technology.
