How to compare multiple variables against one and produce an answer for each comparison?

I calculated 4 different category averages, each is assigned to a variable (ON, BC, QC, & AB), and the total average (CAD). I want to compare each of the 4 averages to the total average, and if it is higher than the total average, it should list the variable name.

Initially I used the code:

fprintf('Areas with averages above the national average: ')
if ON>CAD
    fprintf ('Ontario')
end

but not sure how to repeat this loop for the other 3 variables and produce the same response for all.

"each is assigned to a variable (ON, BC, QC, & AB)"

Storing your data in lots of separate variables nakes this task much more complex.

The name "MATLAB" comes from "MATrix LABoratory", and when you store your data in matrices/vectors, then processing it becomes much easier, as David Hill shows. You should use matrices/vectors, just as MATLAB is designed for.

ON=5;BC=2;QC=4;AB=1;
L=["ON","BC","QC","AB"];%put names in string array
r=[ON,BC,QC,AB];%put all variables into a single array
CAD=mean(r);
L(r>CAD)

ans = 1×2 string array
    "ON"    "QC"
