Try this array formula** :

=MX(IF(Adjusted!$B$3:$B$25="Thu",Adjusted!$I$3:$I$ 25))

** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER). Hold down both the CTRL key and the SHIFT
key then hit ENTER.

I have a spreadsheet that lists usage in our computer lab. From the data I
am able to get the average usage for each day using the averageif function
=AVERAGEIF(Adjusted!$B$3:$B$25,"Thu",Adjusted!$I$3 :$I$25). How can I get
the
max value for each day. There is no maxif or 'if.. then' functions.
