First‚ an observation is made and then a question should be posed about the observation that can be tested and possibly proved false. Next‚ we can make a hypothesis or educated guess about the result cause of the problem. We can then make a prediction on what may fix the issue. The final step would be to test our prediction to find the conclusion. The difference between a scientific based

This will be accepted only when data provides sufficient evidence to establish its truth. 3. Test Statistic - A sample statistic (often a formula) that is used to decide whether to reject H0
