Average Data

Hello,

Still farily new to Power BI, and really green with DAX. Normally in Excel I would create a new row that shows the average of the information, but I am not sure how to do it in Power Bi. Below are pictures of what I have in BI and an excel example that I use. I am able to select the average of a Team in excel and compare it with 1 select individual. In Power BI it shows the average line of all the associated, but when I select the associated it will show just that person and the average of them.
