A testable hypothesis is one that can be used as the basis for an experiment. It predicts the correlation between two variables and can be tested by varying one of the variables. If the variables cannot be measured, the hypothesis cannot be proved or disproved. If one of the variables cannot be varied, it is impossible to conduct an experiment. If more than one variable is changed, the results are inconclusive. To write a testable hypothesis, it is important to consider how it will be tested and what makes for a valid experiment.
A scientific hypothesis is the initial building block in the scientific method. Many describe it as an "educated guess," based on prior knowledge and observation. While this is true, the definition can be expanded. A hypothesis also includes an explanation of why the guess may be correct, according to National Science Teachers Association. A hypothesis is a suggested solution for an unexplained occurrence that does not fit into current accepted scientific theory. The basic idea of a hypothesis is that there is no pre-determined outcome.
