Introduction
- Good experimental design generates information-rich data with a clear message.
Essential Features of a Comparative Experiment
- The raw ingredients of comparative experiments are experimental units, treatments and responses.
Experimental Design Principles
- Replication, randomization and blocking determine the validity and usefulness of an experiment.
Statistics in Data Analysis
- Plotting and significance testing describe patterns in the data and quantify effects against random variation.
Completely Randomized Designs
- CRD is a simple design that can be used when experimental units are homogeneous.
Completely Randomized Design with More than One Treatment Factor
- Completely randomized designs can be structured with two or more factors.
- Random assignment of treatments to experimental units in a single homogeneous group is the same.
- Factorial structure of the experiment requires different analyses, primarily ANOVA.
Randomized Complete Block Designs
- Replication, randomization and blocking determine the validity and usefulness of an experiment.
