All theories are hypotheses, but not all hypotheses are theories. Francis wants to know if a specific hypothesis he is researching is a theory. Which describes how Francis would know the hypothesis is a theory?
Answer
A
He could restate the hypothesis as a fact and no longer an explanation.
B
He could design and perform a new controlled experiment to test the hypothesis.
C
He could perform the experiment and adjust data to match the desired results.
D
He could determine whether the hypothesis is based on repeated experiments.
Explanation
A scientific theory is a well-supported explanation that has been tested repeatedly and is supported by evidence from many investigations. Francis would look for whether the hypothesis has been supported by repeated experiments. A single new experiment can test a hypothesis, but it does not by itself make the hypothesis a theory; changing data to fit a result is not valid scientific practice.
