A fisherman has collected the following data about the length in inches, L, and weight in ounces, w of fish he has caught. The resulting line of best fit for the data is w=−37.1+3.2L
Would predicting the weight of a 26-inch fish be interpolation or extrapolation?
Predicting the weight of a 26-inch fish would be interpolation, as it falls within the range of the data that was used to create the line of best fit. Extrapolation would involve predicting the weight of a fish outside of the range of the data.
