Basic Experimental Design and Data Analysis

The course is designed to acquaint researchers with the principles of experimental design, basic experimental designs used in crop research, analysis of variance and regression and correlation analysis. It also introduces Statistical Tool for Agricultural Research (STAR), a user-friendly software that uses GUI created in Java and functions developed in R to assist crop scientists in the design and analysis of data. The course is intended for researchers in the Agricultural and Biological Sciences. It employs a combination of lecture, group exercises, and hands-on exercises using STAR.

Course Objectives

  • Review basic statistical concepts
  • Describe the three essential components of an experimental design and explain the importance of each component
  • Identify the advantages and disadvantages of using the different experimental designs
  • Generate randomization and electronic field book for basic experimental designs using STAR 
  • Demonstrate how to import tab and comma delimited files into STAR
  • Demonstrate how to sort and reshape data files using STAR
  • Construct analysis of variance table for basic experimental designs and perform the analysis using STAR
  • Perform mean comparison and partitioning of sums of squares 
  • Determine the appropriate transformation for a given set of data
  • Present remedial measures in handling missing data
  • Perform simple correlation and linear regression analysis
