About this app

This application performs a linear fit on the data supplied in X Y format. First, the data for X is entered in one cell and the data for Y is entered in another cell. Numbers must be written separated by commas and without white space. The point is the decimal symbol. Numbers can be entered in decimal or exponential notation (0.000345 or 3.45e-4). Pressing the "Adjust" button performs linear adjustment. The application calculates the line Y=m*X+b that best fits (by least squares) to the data and shows the value of the slope "m" and the ordinate at the origin "b". The errors of these magnitudes and the correlation coefficient "r" that indicates the goodness of the fit are also shown. The graph that includes the data provided and the adjustment line is also shown.
