Question

Fiona wants to test her prediction, also known as a _____, that "lack of sleep increases the likelihood of lower test scores for college students."

Answer 1

The answer is hypothesis.

Step-by-step explanation:

A hypothesis is a possible explanation for a phenomenon. To be regarded as scientific, a hypothesis should be able to be tested.

Although often used interchangeably, a hypothesis is different from a theory. While the former is an educated assumption that can be researched in the future, the latter is a confirmed explanation with scientific basis.
