Hi guys, I'm a new but very impressed Alteryx user. I work with education data and one of the core questions we get from schools is "my 5th graders' average score was a 3.5, is that good?"
The answer is almost always relative and based on a comparison of a given school's (or student's) scores to the average of all other schools or students (eg. same grade, school, district, student type, etc).
Tableau isn't great at creating a benchmark from an average as the basis of comparison, so I am hoping I can create the benchmark average in the data by using Alteryx.
Can anyone point me in the right direction for how to accomplish this in a straight-forward way with Alteryx?
Basically, how do I create a new column that contains the average of a particular measure and level of aggregation?
Thanks, GC, but it's still not totally clear. Let me share a few more details of my use case:
I have survey data, the survey is 39 questions that are in 7 different groupings.
I also have a common education hierarchy: all, school district, school, grade, student.
What I need is the average at every intersection in order to display a "benchmark" against which any level of the school hierarchy can be compared against an benchmark.
For example, if I show a given school's 5th grade average for one of the questions or question groupings, and the score is a 3.5, I need a benchmark average to be able to show that the average score across all 5th graders in the district, or across all 5th graders is X (say, 3.1).
