It’s easy it is to get even simple data wrong

Take a look at that this useful document from Andrew Chen to growing user signups using data and analytical thinking.

There’s a small error but it’s not obvious. Unless you compare it with similar tables.

The error appears in the Baseline Example for the Daily Dairy, in the table on page 8 which displays the answer as 5.6% of new users who post.


But I believe that’s not correct, as when you multiply the variables it gives you the answer 2.8%. Am I right? If I am right it shows how easy it is to get even the simplest of data wrong.
