The purpose of this study is to use deep floor heating to heat the fluid in the installed pipes, which is used to heat water used in homes, factories, workshops, etc. Especially in the city of Tehran and metropolises that have underground trains and some of its lines pass from a depth of 40 meters. That's why measuring the depth of the earth is important. Because it is difficult to get the temperature of the surfaces. It is generally difficult to obtain statistics from experiments and there are not enough statistics to use in statistical calculations, which makes it impossible to make proper inferences. For this reason, using numerical examples, a method will be presented that generates more data from the measured data for use in calculations. This method is also useful for estimating other test data.
