This video explains the connection between the slope of a regression line and the correlation coefficient by examining standardized variables. It demonstrates how the slope of the regression line quantifies an inexact relationship between two variables, while the correlation coefficient measures the strength of the linear association. By standardizing the variables, the slope of the regression line becomes equivalent to the correlation coefficient.
