What part of the scientific method does the 'E' in OQHEAC stand for?

• A. Experiment
• B. Evaluate
• C. Execution
• D. Establish

Answer: (A)

In the acronym OQHEAC, which stands for Observation, Question, Hypothesis, Experiment, Analysis, and Conclusion, the 'E' specifically represents the word "Experiment." This refers to the crucial step in the scientific method where researchers design and carry out controlled tests based on their hypothesis to gather data. The experiment is meant to validate or refute the proposed hypothesis by testing its predictions under controlled conditions.

Conducting the experiment is essential, as it provides empirical evidence that is necessary for analysis. This step often involves manipulating variables and collecting data, which will later be evaluated to draw conclusions about the validity of the hypothesis. The experimental phase is where theory meets practical application, making it a fundamental component of scientific inquiry.
