Basics of Experimental Design

There are several concepts as important to experimental design as they are basic. Perform experiments on any of the following simulated experiments in order to see the importance of some of these concepts illustrated. After each interactive example, if the important concept is not clear, there is a link which, if clicked, will give a detailed explanation.

The following is a java applet designed to illustrate simple concepts of experimental design. Follow the instructions and then click the link below the results to see an explanation of the experimental design concept meant to be illustrated.

 

Our hydrogels are typically prepared at neutral pH, and we've designated the water content at that pH to correspond to 0% swelling. We wish to know if raising or lowering the pH will appreciably affect hydrogel swelling. Select a temperature and then click an arrow to take a measurement.
