Study design, ANOVA vs. regression, fixed vs. random

Hey there!

This is the welcome page for the Kansas State University 2020 AGSA R Workshop - Experimental Design, ANOVA, and Regression, taught by leombastos.

The workshop was divided into 2 days, 2 hours per day:

  • day 1:
    • Intro to completly randomized design (CRD) and randomized complete block design (RCBD)
    • Differences between CRD and RCBD
    • What happens if you run the wrong design ANOVA
    • Should you treat your blocks as fixed or random?
  • day 2:
    • Difference between ANOVA and regression
    • Explore some cool applications of regression like
      • prediction
      • finding an optimum input rate that maximizes yield
