What is the purpose of writing a hypothesis before experimenting?

The purpose of writing a hypothesis before experimenting is to provide a clear and testable prediction about the relationship between variables. It serves as a guiding framework for the experiment, helping to focus the research and establish what is being tested. A well-formulated hypothesis also allows for the identification of expected outcomes, making it easier to analyze results and draw conclusions. Ultimately, it enhances the scientific method by fostering critical thinking and systematic investigation.
