Computer application of the least square method to laboratory physical practice

Authors:

Tatyana Solodchenkova,

Aleksei Delov

The article presents the created program for processing experimental data of laboratory work on physics by the method of least squares. The program is written in C # using Windows Forms in the Visual Studio environment. The program builds graphs of linear dependence, calculates the values of the angle of inclination of the graph and free coefficient, random errors.
