Experimental Research part-4, External Validity & types of Experimental Research design

Experimental Research part-4, External Validity & types of Experimental Research design In this lecture, Dr. Himani Upadhyay explains External Validity and the Types of Experimental Research Designs in a very simple and easy-to-understand way. After understanding internal validity in previous lectures, this session focuses on external validity, which helps researchers know whether the findings of an experiment can be generalized to real-life situations. 🌍 What is External Validity? External validity refers to the generalizability of experimental results — whether the results can be applied to different people, places, and situations. This concept is explained with simple and practical examples. ⚠️ Threats to External Validity: Each threat is explained clearly with examples: Interaction of Selection & Treatment Interaction of Testing & Treatment Interaction of Setting & Treatment Interaction of History & Treatment Reactive Effect of Experimental Arrangements Experimental Bias / Hawthorne Effect Placebo Effect Students will understand how these factors affect the real-world applicability of experiments. 🧪 Types of Experimental Research Design: This lecture also explains the basic differences among experimental designs based on the classification by Campbell & Stanley (1963). You will get a brief and clear understanding of: ✔ Pre-Experimental Designs ✔ True Experimental Designs ✔ Quasi-Experimental Designs Each type is explained in a simple, comparative manner to help students easily remember the differences. 🎓 What You Will Learn: ✔ Meaning of External Validity ✔ Threats to External Validity ✔ Real-life examples of validity threats ✔ Types of Experimental Research Designs ✔ Campbell & Stanley model explained simply 👩‍🏫 About the Educator: Dr. Himani Upadhyay, founder of Shodh Yatra, simplifies complex research methodology topics so students can understand research concepts easily and confidently. 📢 Don’t Forget: 👍 Like | 💬 Comment | 🔔 Subscribe for more Research Methodology lectures external validity, external validity in research, threats to external validity, experimental research part 4, types of experimental design, experimental research design, campbell and stanley 1963, pre experimental design, true experimental design, quasi experimental design, hawthorne effect, placebo effect, experimental bias, research methodology lecture, dr himani upadhyay, shodh yatra, validity in research, experimental research methods, research for students, educational research, experimental design explained, research methodology, external validity examples, generalizability in research
