An hypothesis consists of a group of propositions that collectively form an explanation for a set of observations. If the scientists disagree on the truth of one or more central propositions, they may end up with very different hypotheses to explain the same phenomena.
Scientists collect data through methods such as experiments, observations, and surveys. In experiments, variables are manipulated to observe their effects. Observations involve studying natural phenomena without interference. Surveys gather information through asking questions to a specific group of individuals.
