I am trying to gather information on
the number of questions posted per week for a user with fewer than 25 reputation points from the math.stackexchange site
the weekly average number of up-votes per question for a user with fewer than 25 reputation points.
My approach for the first part is unfortunately not working well: https://data.stackexchange.com/math/query/edit/472455
For the second part, I think I may have been able to accomplish what I have wanted, but I cannot be sure. I am unable to show the date "week + year" of each result. https://data.stackexchange.com/math/query/edit/471895#resultSets
Also, the first part returns 306 rows while the second one returns 304 rows so I suspect that the dates are mismatched.
How would I fix these problems? Also, I was unable to find a "manual" of some sort for the commands.
