Which type of analytics classification uses experimental design and optimization to suggest a course of action?

Descriptive analytics focuses on summarizing historical data to understand what has happened in the past. It employs statistical tools to provide insights into trends and patterns but does not offer recommendations for future actions. Thus, while it is informative, it lacks the prescriptive element that guides decision-making.

Predictive analytics aims to forecast future events based on historical data and statistical algorithms. While it provides insights into potential outcomes, it does not suggest what actions should be taken to influence those outcomes. Therefore, it lacks the directive nature of prescriptive analytics.

Diagnostic analytics seeks to determine the causes of past events by analyzing data and identifying relationships. It explains why something happened but does not make recommendations for future actions. Thus, it is more about understanding past events rather than prescribing future actions.
