You're gonna shoot me when you see how easy this is:
anArray := #(12 14 16 18 20). theAverage := (anArray sum) / (anArray size)
Learn to use the method finder. Helps tremendously.
Yep. In this case, you know the input is #(12 14 16 18 20) and the output will be 16, so you can enter this into the upper left pane of the Method Finder:
#(12 14 16 18 20). 16
This will reveal three methods that will yield that result:
#(12 14 16 18 20) average --> 16 #(12 14 16 18 20) median --> 16 #(12 14 16 18 20) third --> 16
Fun stuff! Someone really needs to write up a beginner's tutorial for the Method Finder.
