Verified step by step guidance

Begin with Observation: This is the initial step where you gather information through your senses or instruments about a phenomenon or problem.

Formulate a Hypothesis: Based on your observations, propose a tentative explanation or prediction that can be tested through experimentation.

Conduct an Experiment: Design and perform experiments to test the hypothesis. This involves manipulating variables and collecting data to see if the hypothesis holds true.

Perform Data Analysis: Analyze the data collected from the experiments to determine whether they support or refute the hypothesis. This may involve statistical analysis or other methods to interpret the results.

Draw a Conclusion: Based on the data analysis, decide whether the hypothesis is supported or not. This step involves summarizing the findings and considering their implications.

Engage in Peer Review & Publish: Share your findings with the scientific community for validation and feedback. Publishing allows others to review and build upon your work.
