Scatterplot: A scatterplot is a graph that displays the relationship between two variables by plotting their values on a Cartesian plane. It helps visualize correlations.
Pearson's Correlation Coefficient: This coefficient quantifies the strength and direction of the linear relationship between two variables. It ranges from -1 to 1.
Causation: While correlations show a relationship between variables, causation refers to one variable directly causing changes in another variable.
