Experimental Research - Part 3 Statistical Manipulation & Internal Validity

Описание: Experimental Research – Part 3: Statistical Manipulation & Internal Validity

In this lecture, Dr. Himani Upadhyay explains an important topic of experimental research — Statistical Manipulation and Internal Validity — in a very simple and easy-to-understand way.

This session helps students understand how researchers control complex variables using statistical methods and how to maintain the accuracy and reliability of experiments.

📊 Statistical Manipulation Explained:

Some variables like intelligence, aptitude, study habits, stress, anxiety, and fear of failure cannot be controlled physically. These variables are controlled using statistical techniques, such as:
✔ Analysis of Covariance (ANCOVA)
✔ Partial Correlation

These concepts are explained with simple and practical examples so that students can easily understand how statistical control works in real research situations.

🎯 Internal Validity Explained:

What is Internal Validity and why is it important in experimental research?
This lecture explains how to increase internal validity and ensure that the results of an experiment are truly reliable.

⚠️ Factors Affecting Internal Validity:

Each factor is explained in very simple language with examples:
1️⃣ History
2️⃣ Maturation
3️⃣ Selection
4️⃣ Testing Effect
5️⃣ Instrumentation Effect
6️⃣ Statistical Regression
7️⃣ Experimental Mortality
8️⃣ Selection–Maturation Interaction

Students will clearly understand how these factors influence experimental results and how researchers can control them.

🎓 What You Will Learn:

✔ Statistical control of variables
✔ Meaning of internal validity
✔ How to make experiments more accurate
✔ Threats to internal validity
✔ Practical research examples
