How to use hypothesis
A hypothesis is an educated guess or tentative explanation that precedes investigation or experimentation, particularly in scientific contexts. It differs from theory in that a theory has substantial supporting evidence, while a hypothesis is preliminary and awaits testing. The term is used in both formal research and everyday reasoning about unproven ideas.

A common mistake
