Khan Academy: Linear Regression Review
Linear regression is a process of drawing a line through data in a scatter plot. The line summarizes the data, which is useful when making predictions.
Khan Academy
Khan Academy: Correlation Coefficient Review
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 computations. We focus on understanding what r says about a scatterplot.
