A hypothesis is a statement that can be tested by scientific research. He was wrong. This means a hypothesis is the stepping stone to a soon-to-be proven theory. It includes components like variables, population and the relation between the variables. Then the theory is modified or even to be replaced by a new theory. How light travels rectilinearly while curving. If a person gets 7 hours of sleep, then he will feel less fatigue than if he sleeps less. your hypothesis may be subject to strong dependent variable such as electricity which is epileptic in most developing country and as such may hinder refrigeration.

The null hypothesis is the default position that there is no association between the variables.
Science > Physics > Introduction to Physics. The hypothesis must be specific and should have scope for conducting more tests.

If the hypothesis is a relational hypothesis, then it should be stating the relationship between variables. In this example, the independent variable is apple consumption — the assumed cause. It becomes the start point for the investigation.
