Hi @LauraBoagey1 

You will want to use the "Mean" function, which you can find more information on here: Math functions | ArcGIS Arcade | ArcGIS Developers

As an example, you will see I have created a calculated expression for one of my fields in field maps to be the mean of my first two questions:

Hopefully this helps, let me know if you have any questions!

Go to Styles, click the Expression button, use something like (updating it with all your fields):

Round(Average([$feature.field1,$feature.field2,$feature.field2. $feature........]),0)

Pick Types (unique symbols) for the style.

Then, click the three dots next to Title and Add Value to add the values/symbols you want.
