IGNOU MA Psychology MAPC | MPC-006 Statistics | Block-2 Unit-1 Part-3 Correlation | Dr Shivi Tyagi

Описание: This video is part of the IGNOU MAPC (MA Psychology) programme and covers MPC-006: Statistics in Psychology – Block-2: Correlation and Regression, Unit-1 (Product Moment Coefficient of Correlation).
In this lecture, Dr. Shivi Tyagi (Assistant Professor) explains the concept, interpretation, and computation of correlation, with special emphasis on Pearson’s Product Moment Coefficient of Correlation, in a clear, systematic, and exam-focused manner.

The session begins with the meaning and interpretation of correlation, including graphical representation through scatter diagrams, types of relationships (linear and non-linear), direction and strength of correlation, and the distinction between correlation and causality. It then moves on to the measurement of correlation, laying a strong conceptual foundation.

A major part of the lecture is devoted to Pearson’s Product Moment Coefficient of Correlation, covering its theoretical basis (variance and covariance), formulas, step-by-step numerical examples, and significance testing of Pearson’s r. Important conceptual issues such as adjusted r, assumptions for significance testing, restricted range, outliers, curvilinearity, and unreliability of measurement are also discussed to help students avoid common errors in interpretation.

The lecture also explains the raw score method for calculating Pearson’s r, including relevant formulas and solved numerical problems, making it especially useful for exam preparation and assignments.

This session is designed specifically for IGNOU MAPC students, keeping in mind:

• Strict IGNOU syllabus alignment
• Coverage of Previous Year Questions (PYQs)
• Conceptual clarity along with numerical problem-solving
• Step-by-step explanations for learners new to statistics

A clear understanding of correlation is essential for psychological research, data analysis, and interpretation, and this lecture helps learners build that foundation confidently.
