Statistics for Data Science and Business Analysis - The Correlation Coefficient

The video tutorial explains the concept of correlation coefficient, its calculation using covariance and standard deviations, and the interpretation of correlation values. It highlights the impossibility of correlation values exceeding one or being less than minus one, and provides examples of positive, negative, and zero correlations. The tutorial also discusses the symmetry of correlation and the importance of understanding causality, particularly in the context of housing prices and size. The section concludes with a reminder that correlation does not imply causation and previews the next lesson on applying these concepts to a real-life database example.
