Which chart or graph should I use to represent this data?
- # of emails sent (100)
- # of responses to emails (30)
- Of those responses (30), the # of people who took action (10)
I am being asked to show the conversion rates.
You could show something similar to how HotJar does it:
The line progression clearly shows drop-off, while it tells both % and amount. Furthermore, it also shows how many made it to the next stage and the %.
Your chart numbers would be something like this:
100 | 30 (30% of 100) (70% of 100 drop-off) | 10 (33% of 30) (67% of 30 drop-off)
