Creating daily conversion rate DataFrame

To understand trends over time, you will create a new DataFrame that includes the conversion rate each day. You will follow essentially the same steps as before when you calculated the overall conversion rate, this time also grouping by the date a user subscribed.

Looking at the daily conversion rate is crucial to contextualize whether the conversion rate on a particular day was good or bad. Additionally, looking at conversion rate over time can help to surface trends such as a conversion rate that appears to be going down over time. These kinds of trends are crucial to identify for your marketing stakeholders as early as possible.
