I’d like to know how to calculate percentage in the Joining Tables (Chapter 6) Freeform Project?
It starts with number 5, but the rest of the questions will ask us to exercise doing it again.
There’s a hint saying: " You can find the percentage of users who put items in their cart but did not proceed to checkout by counting the
NA values of
checkout_time and comparing it to the total number of users who put items in their cart"
I’m trying to figure out the command from the hint. Please let me know if anyone can help!
