A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. Even though the words "hypothesis" and "theory" are often used synonymously, a scientific hypothesis is not the same as a scientific theory. A working hypothesis is a provisionally accepted hypothesis proposed for further research.
A different meaning of the term hypothesis is used in formal logic, to denote the antecedent of a proposition; thus in the proposition "If P, then Q", P denotes the hypothesis (or antecedent); Q can be called a consequent. P is the assumption in a (possibly counterfactual) What If question.
The adjective hypothetical, meaning "having the nature of a hypothesis", or "being assumed to exist as an immediate consequence of a hypothesis", can refer to any of these meanings of the term "hypothesis".

We will discuss terms such as the null hypothesis, the alternate hypothesis, statistical significance of a hypothesis test, and more. In this step-by-step statistics tutorial, the student will learn how to perform hypothesis testing in statistics by working examples and solved problems.

Stop saying it like it’s a bad thing! It’s time we learn the difference between a fact, a theory, a hypothesis, and a scientific law.

Are we living in a virtual reality? Is the universe emerging from an information processing system? And if so, could we ever tell? Is it possible to 'hack' the system and change reality? Take a look at the evidence and decide for yourself! Contributions to THE SIMULATION HYPOTHESIS are made by leading researchers from physics, cosmology, mathematics and information sciences. Appearances by MaxTegmark, Neil degrasse Tyson, Paul Davies, James Gates and many more. Science has never been so much fun! “What an incredible film!

http://www.sciencefriday.com t's not just generations of children who have pondered how many licks it takes to reach the center of a lollipop. Mathematicians studying fluid dynamics at NYU's Applied Mathematics Lab designed experiments to watch how lollipops dissolve, and in doing so answered this epic childhood question. Help test their results by taking the Science Friday Lollipop Challenge! Produced by Emily V.

You say you're going up to higher ground,
You say you're going up to higher ground,
To higher ground
I don't think your hypothesis is very sound,
I don't think your hypothesis is very sound,
Is very sound
You don't mind the nails in your hands,
I prefer the needles in my back,
In my back
If I could just make one suggestion,
Perhaps start with experimentation,
