16. How do you write a hypothesis?

You use the words "if" and "then"

To write a hypothesis, you can create an "if-then" statement that indicates directionality, or you may also use the null/alternative hypothesis.

Examples:

If-then: If you get at least 6 hours of sleep, you will do better on tests than if you get less sleep.

Null: The number of pets in a household is unrelated to the number of people living in it.

Alternative: The chemicals will affect the plants.
