How effective are loyalty programs in improving customer retention? Write about a loyalty program that you personally find to be particularly effective (or ineffective). If you don’t have any personal experience to write about, that’s okay — you can look one up, and then write about it.
Write about a time when you felt a strong reaction to a feature changing on a website or app that you frequently use. Did you love the change, or hate the change? Why? Speculate about the other versions of the feature that could have been used in an A/B test.
Make up your own example of a situation in which a marketer might wish to perform a chi-square goodness of fit test to assess an experiment. Randomly generate values for your scenario using numpy. Run a chi-square goodness of fit test in Python to assess the null hypothesis. (you may either upload an HTML file generated in Jupyter Notebook that includes your code, results, and written statements, or a screenshot of your results in Jupyter along with your written statements — either way is fine).
