Definitions:

Hypothesis

A hypothesis is a proposed explanation or assumption for a phenomenon or a relationship between variables that can be tested through research and experimentation.

Null Hypothesis

The null hypothesis is a statement in statistics that suggests no significant effect or relationship exists in the population; it is the hypothesis that a statistical test aims to disprove.

Alternative Hypothesis

In hypothesis testing, the hypothesis that there is a significant difference between specified populations, which is considered if the null hypothesis is rejected.

Statistical Evidence

Data or information collected during an experimental or observational study that supports or refutes a statistical hypothesis.
