Average users per group
Good morning! I am just starting to use PowerBI and DAX, and have been frustrated by what seems like it should be an easy thing.
Given a table like this:
| Group_Name | Group_ID | User_ID |
| Group 1 | 1 | 100 |
| Group 1 | 1 | 200 |
| Group 1 | 1 | 300 |
| Group 2 | 2 | 100 |
I want to calculate the average number of people per group. In this case "2" ((3 + 1)/2). I've tried setting up a second table based using SUMMARIZE, so it ends up like:
| Group_ID | UserCount |
| 1 | 3 |
| 2 | 1 |
And then tried to calculate the AVERAGE of that new table. But my SUMMARIZE never turns out right.
SUMMARIZE(group_user_links,group_user_links[group_id], "UserCount", DISTINCTCOUNT(group_user_links[user_id])) or
SUMMARIZE(group_user_links,group_user_links[group_id], "UserCount", COUNTX(group_user_links, group_user_links[user_id])) end up way too high.
Is that the best way to go about it? Or is there a better way?
