Why research needs to test hypotheses or create hypotheses?

Nice to learn it.

I appreciate your response.

Research needs to test or create hypotheses for the following reasons:

Focused inquiry: Hypotheses provide a clear focus and direction for research. They help researchers narrow down their investigation to specific variables or relationships, guiding the research process and ensuring a systematic approach.

Testable predictions: Hypotheses allow researchers to make testable predictions about the expected outcomes or relationships between variables. Testing hypotheses provides empirical evidence to support or refute these predictions, contributing to the advancement of knowledge.

Rigorous methodology: Hypotheses help establish a rigorous methodology for research. They guide the selection of appropriate research designs, data collection methods, and statistical analyses, ensuring the research is conducted systematically and objectively.

Theory development: Hypotheses play a vital role in theory development. Testing hypotheses allows researchers to evaluate and refine existing theories or propose new ones, contributing to the growth and evolution of scientific knowledge.

Evidence-based decision making: Testing hypotheses provides evidence to inform decision-making processes. By systematically testing hypotheses, researchers generate empirical data that can be used to make informed decisions in various fields, including medicine, policy-making, and education.
