Quizplus · Accepted Answer

A hypothesis is a possible explanation that can be tested through scientific investigation. It is based on prior knowledge or observations and is used to form predictions about the outcome of experiments. An opinion is a personal belief or judgment that may not be based on evidence or facts. A set of observations that need explanation is more akin to a problem or phenomenon. An experiment is a procedure used to test a hypothesis. An idea that has been rejected is not a hypothesis anymore since it has already been shown to be incorrect.
