Assessing the Strength of Linear Association with Correlation Coefficient

The video tutorial explains how to assess the strength of a linear association using the correlation coefficient. It covers the basics of scatterplots, types of correlation (positive, negative, and none), and how the correlation coefficient (r) is calculated and interpreted. Examples are provided to illustrate different levels of correlation, including perfect, strong, moderate, weak, and no correlation. The tutorial emphasizes that the correlation coefficient only measures linear relationships and provides guidelines for interpreting its value.
