A hypothesis is a tentative statement about the relationship between two or more variables. It is a specific, testable prediction about what you expect to happen in a study.
Why is a hypothesis a testable statement?
A hypothesis is an educated guess or prediction about the relationship between two variables. It must be a testable statement; something that you can support or falsify with observable evidence. The objective of a hypothesis is for an idea to be tested, not proven.
Is the hypothesis testable?

What is the best definition of hypothesis?
A hypothesis is an assumption, an idea that is proposed for the sake of argument so that it can be tested to see if it might be true.

Which of the following is the best definition of a hypothesis?
In science, a hypothesis is an idea or explanation that you then test through study and experimentation. Outside science, a theory or guess can also be called a hypothesis.

What is an example of a testable hypothesis?
If you put people in a dark room, then they will be unable to tell when an infrared light turns on. This hypothesis is testable because it is possible to put a group of people into a dark room, turn on an infrared light, and ask the people in the room whether or not an infrared light has been turned on.
What are examples of hypothesis?

- If garlic repels fleas, then a dog that is given garlic every day will not get fleas.

What is your hypothesis for this experiment?
The hypothesis is an educated guess as to what will happen during your experiment. The hypothesis is often written using the words “IF” and “THEN.” For example, “If I do not study, then I will fail the test.” The “if’ and “then” statements reflect your independent and dependent variables.
Do all hypotheses have to be testable?
Whenever you create a hypothesis to prove a part of a theory, it must be testable and analyzable with current technology. You may develop a great hypothesis to try to verify part of a theory but, if it involves a lot of resources and money that you do not have, it is effectively invalid.
Does a hypothesis have to be true?
A hypothesis is a statement assumed to be true. The researcher cannot prove that any hypothesis is true, but can only prove that it is false by presenting evidence to the contrary. A hypothesis proposes the reason for the observation of an event. It must be an informed judgment that is debatable or open for discussion of its pros and cons.
