The two ways a hypothesis can be tested are by; performing controlled experiments or by gathering more data.
Hypothesis
A scientific explanation for a set of observations that can be tested in ways that support it or reject it is called a hypothesis. A hypothesis is a proposed explanation for a phenomenon that can be tested through experiments or observations to determine its validity.
