Step 4 of DOE
Conclusion or Contextual Conclusion is drawn to interpret the results in the context of the problem for an eighth grader. For an example, Figure 3 (in SECTION 4. Step 3 of DOE Results) show the results in a way so that anyone could understand, while the method and results steps are hidden due to the complexity and interests to its audience. In most situations, results are presented for the general audience which demands for an eighth grader level interpretations. Whether there is a significant result or not, the final step of any research study is to produce some future directions, including making new, well informed, and better hypotheses. Therefore, the design of experiment procedure has been developed for continual improvement as described in Figure 4.
