Find the function that best expresses the data set with the numerical methods approach by creating an experimental data set based on 10 measurements related to your engineering discipline. Find the function again of the same data set using Excel. Compare both methods using the function and error value, the regression parameter R2.

I found a dataset as shown in the image.
