Mathematica: Hubble

Enter the Hubble data hubble = {{0.032, 170}, {0.034, 290}, {0.214, -130}, {0.263, -70}, {0.275, -185}, {0.275, -220}, {0.45, 200}, {0.50, 290}, {0.50, 270}, {0.63, 200}, {0.8, 300}, {0.9, -30}, {0.9, 650}, {0.9, 150 }, {0.9, 500}, {1, 920}, {1.1, 450}, {1.1, 500}, {1.4, 500}, {1.7, 960}, {2, 500}, {2, 850}, {2, 800}, {2, 1090}}

Make a ListPlot of the Hubble data

Click on the label button from the suggestions that arise

Result of adding labels

Use the LinearModelFit – linear here means that it is linear in the fit parameters

The ParameterTable option gets some of the statistical measures for the fit

Use Normal to extract the simple fit formula from all the associated statistical data. Then plot the fit function

Use Show to put the ListPlot of the data and the Plot of the fit formula together

We can get the equation displayed as well
