WebEstimating a value outside a set of data points. Example: we sell: • 100 ice creams when it is 20°C, • 200 ice creams when it is 25°C, so we could extrapolate: • 300 ice creams when it is 30°C (but we may be wrong) Here is another example of extrapolation: WebDec 4, 2014 · Extrapolation is a risky business with or without a model. For example, consider models of population, ocean temperatures, global temperatures, etc. As much as people try, you need a good model of your process, one that explains it well. Otherwise, you will get random predictions, or at best, completely arbitrary ones.
