must be testable
must have only 1 testable variable
can test many variables at one time
must be repeatable

Explanation:

A hypothesis is an educated guess based on prior knowledge. It is often phrased as an "If - then" statement. It must be testable to be valid in an experiment, and while it can focus on one main testable variable, it doesn't mean only one variable can be involved in the experiment overall. Also, for the results to be reliable, the experiment based on the hypothesis should be repeatable.

Answer:

Hypothesis is an "educated guess", Is properly phrased as and "If, then " statement, Must be testable, Must be repeatable
