Scatter Plot: A scatter plot is a graph that displays individual data points for two variables. It helps visualize relationships between variables.
Residuals: Residuals are the differences between observed data points and predicted values on the line of best fit. They measure how well the line fits the data.
Extrapolation: Extrapolation involves extending the line of best fit beyond the range of observed data to make predictions. However, it can be less reliable than interpolation within the observed range.
