When planning any science research project to gain information for a particular goal or objective, much thought is placed into what is called the experimental design or layout of the experiment. This is important to ensure the researcher is able to obtain useful data which can later be analyzed and provide information as to whether or not the scientific hypothesis being tested is supported or rejected. In this eLesson series we will look at a plant breeding experiment which uses the Augmented Design and utilize tools in R to analyze the data.

After completing this lesson, you will be able to :

  1. Understand details of the Augmented Design used in the experiment discussed in this eLesson.
  2. Describe critical elements of a Linear Mixed Model viz. the Fixed Effects and the Random Effects.
  3. Explain how Linear Mixed Modeling plays a role in the research scenario depicted in this lesson.
