Some good places to look for information are textbooks, the Internet, and the library. Especially in the physical sciences, non-directional predictions are often seen as inadequate. These are your research questions. Surprisingly, scientists seldom succeed in demonstrating the veracity or falsehood of a hypothesis. If you do indeed confirm that red is the most popular color, your next step may be to ask: Why is red the most popular color? Hypotheses can either be directional or non-directional.

These instructions will help get you started. But the alternative hypothesis is harder to propose and test. A plural hypotheses is a proposed explanation for an observation.
