Define Hypothesis.

A hypothesis is a tentative and testable statement or proposition that serves as the foundation for scientific investigation and experimentation. It is an essential component of the scientific method, guiding researchers in formulating predictions and designing experiments to empirically test the validity of the hypothesis.

A well-constructed hypothesis typically comprises two main components: the independent variable, which is manipulated or changed by the researcher, and the dependent variable, which is the outcome or response that is measured. The hypothesis also establishes a cause-and-effect relationship between the variables.

Hypotheses play a crucial role in shaping the research process. They provide a clear and specific focus, helping researchers articulate their expectations and predictions based on existing knowledge or theories. Through empirical testing and observation, hypotheses enable scientists to draw conclusions about the validity of their ideas and contribute to the cumulative body of scientific knowledge.

As research progresses, hypotheses may be refined, revised, or rejected based on the evidence gathered. The formulation and testing of hypotheses are integral steps in the systematic and logical approach that characterizes scientific inquiry, allowing for the advancement and refinement of our understanding of the natural world.
