Lesson 9: ANCOVA II

Overview Section

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.

Objectives

Upon completion of this lesson, you should be able to:

  • 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.
