A hypothesis is a possible explanation for a set of observations or an answer to a scientific question. … This means that researchers must be able to carry out investi- gations and gather evidence that will either support or disprove the hypothesis. Many trials will be needed before a hypothesis can be accepted as
true
.

posits an expected relationship between variables and clearly states a relationship between variables
. … A hypothesis should be brief and to the point. You want the research hypothesis to describe the relationship between variables and to be as direct and explicit as possible.

it is possible to conceive of an experimental observation that disproves the idea in question
. That is, one of the possible outcomes of the designed experiment must be an answer, that if obtained, would disprove the hypothesis.
