A hypothesis is a statement proposed to be tested in an experiment. It’s an educated guess about a cause–effect relationship or a specific outcome under defined conditions, and it makes a concrete prediction that can be measured. Its value lies in being testable and falsifiable, so you can design experiments to see whether the results support or refute it. After gathering and analyzing data, you decide whether the results align with the prediction, leading to support, revision, or rejection of the hypothesis. The other terms have different roles: a theory is a broad, well-supported explanation built from many tested ideas; a conclusion is the result drawn from data after analysis; an observation is simply noticing and recording something you see.
