1-Key Concepts
- An Intervention is a deliberate change in a system to observe its impact;
- Controlled Experiments: use treatment and control groups to isolate the effect of the intervention.
- Uncontrolled Experiments : no comparision group , making it harder to infer causality.
2-Types of Intervention Experiments
- Randomized Controlled Trials(RCTs);
- Quasi-Experiments
- A/B Testing (Used in Business & Tech)
3-Steps in an Intervention Experiment
- Define the Research Question;
- Design the Experiment;
- Assign Participants or Subjects;
- Implement the Intervention;
- Collect Data;
- Analyze Results;
- Interpret Findings & Optimize Future Interventions;
4-Application of Intervention Experiments
- Healthcare: Testing new treatments, vaccines or public health policies;
- Economics & Policy : Evaluating tax reforms , social programs or labor laws;
- Education: Measuring the impact of new teaching methods on learning outcomes;
- Technology & AI : A/B testing in user experience (UX) and algorithm optimization;
