Create a dataset and then fit a line to it. Present a hypothesis, get the data, determine the fit. Your data can be anything. you can be creative. You could interview friends to get data points. You can search online. You can make it as fun as you want. But I want at least 5 data points that you generate from your ideas and hypotheses. Make it look good! Then you have to write a figure caption and summary sentences about your results in markdown. This can all be in one ipython notebook. The results should be presented from both your method for fitting a line and a python method for fitting a line. You should make sure that your line fitting algorithm and the python algorithm give the same answer.
