These earlier sections provide much of the context and justification for the predictions. The null hypothesis itself does not involve the data.

However, a theory does not need to be supported to be a theory. Bacterial growth may be affected by temperature.

Among the factors to consider when formulating your hypothesis, is your statement can be tested by a different person or is the statement is based on research and facts that can be verified.
