A scatterplot is a graph used to show the relationship between two variables. It plots points for each pair of values from two different data sets. Good scatterplots are properly labeled and use consistent intervals on the axes. Scatterplots can show strong, weak, or no correlation between the variables. Outliers are distant data points that may influence correlation. Real-world examples include using scatterplots to examine relationships between US population and time over decades.
