Chapter Overview

Concept

A fair test isolates the change

Click to zoomIllustration supporting A fair test isolates the change

To test whether one factor matters, keep other important conditions similar. Change one variable, use a comparison and measure the outcome the same way.

Example

Keeping fruit fresh

If one apple is refrigerated and another is left in sunlight, both temperature and sunlight change. A better test changes storage method while keeping fruit type, ripeness, time and measurement consistent.
