Choose a topic and hypothesis of your choice, find an appropriate dataset, estimate a regression model, and present your model and results in a written academic essay (i.e. term paper). You can choose any topic or dataset that might interest you. If you need some inspiration, https://ourworldindata.org/ has fascinating long-run datasets, but you are welcome to use any data to answer any question you are interested in (for example: does smoking affect babies’ birthweight? Has the introduction of airbags/seatbelts lowered car accident deaths? Has the BC carbon tax lowered CO2 emissions? etc.).
