Sal explains the intuition behind correlation coefficients and does a problem where he matches correlation coefficients to scatter plots.

What is a correlation coefficient? The correlation coefficient r measures the direction and strength of a linear relationship. Calculating r is pretty complex, so we usually rely on technology for the …

What is correlation? We often see patterns or relationships in scatterplots. When the y variable tends to increase as the x variable increases, we say there is a positive correlation between …

How is it possible to tell whether the correlation is strong or moderately strong?

If there is a correlation between two variables, a pattern can be seen when the variables are plotted on a scatterplot. If this pattern can be approximated by a line, the correlation is linear.

Match correlation coefficients to scatterplots to build a deeper intuition behind correlation coefficients.

We use scatter plots to explore the relationship between two quantitative variables, and we use regression to model the relationship and make predictions. This unit explores linear regression …
