In Lewis's model, what is the correct order of the stages Observe, Hypothesise, and Experiment?

• A. Observe, Hypothesise, Experiment
• B. Hypothesise, Observe, Experiment
• C. Experiment, Observe, Hypothesise
• D. Observe, Experiment, Hypothesise

Answer: (A)

In Lewis's approach, you start by Observe because you need real evidence about what’s happening. Seeing the facts, patterns, and any irregularities gives you a solid foundation to build on. Once you’ve gathered enough data from those observations, you can form a Hypothesise—a testable explanation or educated guess about why the observations occurred and what you would expect to happen under certain conditions. The next step is to Experiment, where you test that hypothesis through controlled testing and data collection to see if the results support or challenge your guess. If the outcomes match the prediction, the hypothesis has support; if they don’t, you refine the idea and test again. Jumping straight to Hypothesise without first observing leaves you guessing without evidence, and starting with Experiment without a guiding hypothesis risks unfocused tests. So the correct order is Observe, Hypothesise, Experiment.
