Google Analyitcs tracking of Flubaroo usage may be flawed #12

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I'm not 100% convinced that my GA code is perfect. For example, when I only 
ever track "first install" once, and see therefore that my number of page views 
and unique page views for "/First Install" per day is always the same. This is 
as it should be, since someone can't do a "first install" more than once.

But for grading, I see that my number of page views is almost always 2x my 
number of unique page views. This is very consistent. This either means that 
most users grade the 2x per day (perhaps usually regrading the same 
assignment?), or that something is funky with my GA code and how it identifies 
unique users. Attached is yesterday's data.

Further clarification,  based on attached image:

217 * 2 = 434, which is just over 426. I always see this type of issue. It's 
almost like 98% of users are grading 2x per day. Seems plausible sometimes, but 
the consistency with which I see it troubles me.

I don't see a problem in the code at first inspection.  The logGrading() 
function is getting called only once in the grading process (I ran a 
Logger.log("graded")) just after the logGrading function and only one result 
returned.

I set up a separate analytics account to test as well, and only saw the live 
analytics recorded register once from the grading process.

My only thought is that 98% of schools have attendance rates below 100%, so 
there's a 98% chance that at least one student is absent from a course on the 
day of a quiz, meaning that 98% of quizzes require regrading.

Plausible explanation. Thanks for checking into this Andrew!

Leaving this be. I am tracking active users another way now, as of Flubaroo 3.0.
