Part G: Interpolation and Extrapolation Graphs can be very useful to identify trends that occur in experimental data. Trends in data can also be used to make predictions about where additional data points might occur if more experimental trials are conducted. You can use the data presented in graphs to make two general types of predictions. An interpolation is a prediction made between known data points. An extrapolation is a prediction made beyond known data points. Use the graph to fill in the blanks in the data table.
