How do you gather data to answer a hypothesis?

To gather data to answer a hypothesis, first, define the research question clearly and formulate a testable hypothesis. Then, select an appropriate research design, which may include experiments, surveys, or observational studies, depending on the nature of the hypothesis. Collect data using systematic methods, ensuring that the sample size is adequate and that data collection tools are reliable and valid. Finally, analyze the data using statistical methods to determine whether the evidence supports or refutes the hypothesis.
