Hypothesis Definition


Definition: A hypothesis is an explanation that is proposed for a phenomenon. Formulating a hypothesis is a step of the scientific method.

Alternate Spellings: plural: hypotheses

Examples: Upon observing that a lake appears blue under a blue sky, you might propose the hypothesis that the lake is blue because it is reflecting the sky. One alternate hypothesis would be that the lake is blue because water is blue.
