Example
Extrapolation explained with an example
For example, suppose a data set consists of four given values: 1, 3, 5 and 7. If these values were plotted on a graph and the line was expected to continue in the same way, the fifth value could be extrapolated as 9. In this method, the last value is not known with certainty.

How to
In the case of linear extrapolation, the data points are plotted on a graph and a linear equation is used to best represent the data. Then to extrapolate for a value close to the existing data, the line is extended and the concerned value of the dependent variable is calculated for the concerned independent variable.Nov 18, 2021
Formula
Techniques
Extrapolation is a statistical technique used in data science to estimate values of data points beyond the range of the known values in the data set. Abdishakur Hassan is an urban planning and geospatial data science consultant.Feb 6, 2023
