Hypothesis free research and reproducibility. Scientists use null and alternative hypotheses to explore relationships between variables in experiments. It acts as a starting point, guiding researchers to examine whether their predictions hold true based on collected data. May 6, 2022 · A hypothesis is a statement that can be tested by scientific research. It suggests how one variable (the independent variable) affects another (the dependent variable). In the scientific method, the hypothesis is constructed before any applicable research has been done, apart from a basic background review. .

It is a preliminary answer to your question that helps guide the research process. Aug 13, 2025 · The two primary features of a scientific hypothesis are falsifiability and testability, which are reflected in an “If…then” statement summarizing the idea and in the ability to be supported or refuted through observation and experimentation. If you want to test a relationship between two or more variables, you need to write hypotheses before you start your experiment or data collection. In formal logic, a hypothesis is the antecedent in a proposition. It’s not just a random statement—it’s based on existing knowledge, prior experience, or preliminary data. Jun 22, 2023 · A hypothesis is a statement that explains the predictions and reasoning of your research—an “educated guess” about how your scientific experiments will end. It is a specific, testable prediction about what you expect to happen in a study. A hypothesis is an assumption, an idea that is proposed for the sake of argument so that it can be tested to see if it might be true.
