Hypothesis:
1.
A supposition or explanation (theory)
that is provisionally accepted in orderto interpret certain events or
phenomena, and to provide guidance for further investigation. A
hypothesis may be proven correct or wrong, and must be capable of refutation.
If it remains unrefuted by facts, it is said to be verified or
corroborated.

2. Statistics: An assumption about certain characteristics of a population. If it specifies values for every parameter of a population, it is called a simple hypothesis; if not, a composite hypothesis. If it attempts to nullify the difference between two sample means (by suggesting that the difference is of no statistical significance), it is called a null hypothesis.
