Query to Sort by Popularity

I read the previous support question regarding sorting by popularity: https://ww.wp.xz.cn/support/topic/list-top-questions-on-another-page-1?replies=2.

Here you say that if there is another plugin calculating the data than a query can be written.

I have added the GA Analytics plugin. Where would I find out how to write the query?
