Hypothesis testing is a branch of statistics in which an inference is made about a population parameter or a population probability distribution using data from a sample. Let’s examine the purpose of ...

Intriguing signs from CERN hint at a never-before-seen form of matter – one that could be the tiniest particle cluster ever detected. Top quarks, typically too short-lived to pair up, may have briefly ...

To do this, we state null and alternative hypotheses. These are two competing statements. The null hypothesis (called H0) usually follows the format that “there is no difference between these numbers” ...

Most of us are not scientists. Most of us know so little about any particular area of scientific research that we have no ...

Students will analyze information from a variety of sources in order to create a hypothesis about the origin of an interesting family artifact. Students will create alternative hypotheses based ...

The CMS collaboration at CERN has observed an unexpected feature in data produced by the Large Hadron Collider (LHC), which could point to the existence of the smallest composite particle yet observed ...
