A refutable hypothesis must ____. a. refer to variables that can be observed or measured b. make a positive statement about the
existence of an effect or a relationship c. allow for the possibility that the observations will not support the hypothesis d. state at least one conclusion that has already been proven
The answer is c. allow for the possibility that the observations will not support the hypothesis.
Explanation:
A refutable hypothesis must allow for the possibility that the observations will not support the hypothesis: this is true because the main characteristics of any hypothesis are that it should be testable and falsifiable: observations related to the hypothesis can be tested, and could fail or be proved wrong.
Answer: ALLOW FOR THE POSSIBILITY THAT THE OBSERVATIONS WILL NOT SUPPORT THE HYPOTHESIS.
Explanation: Basically, a refutable hypothesis can be said to be an assumption taken to be true for the purpose of argument or investigation that can be proven to be false or incorrect.
The statement, "allow for the possibility that the observations will not support the hypothesis" is more or less a paraphrase of the definition of a refutable hypothesis.
