The term 'experimental design' refers to a plan for assigning experimental units to treatment conditions. A good experimental design serves three purposes.

In this Module, you will learn how to use experimental design.

Next, you will become familiar with chi-square tests which tests for different purposes. A chi-square test, for testing goodness of fit, is used to decide whether there is any difference between the observed (experimental) value and the expected (theoretical) value. For example, given a sample, we may like to test if it has been drawn from a normal population.

Lastly, we bring the whole course together by learning about the powerful tool of regression analysis.
