to investigate user behavior for the company’s app (a startup that sells food products).
First we will preprocess the data and study the sales funnel:
find out how users reach the purchase stage
How many users actually make it to this stage
how many get stuck at previous stages
Next we will check the results of an A/A/B test: if change of the fonts for the entire app have any impact on users. We will pick up the equal number of users for all 3 groups and run a statistical test to check if there is a statistically significant difference in number of users for any of the events.
