Maybe this is obvious to others, but I need a little bit of clarification for this query. I know it has to do with the amount spent on a project, but I'm not sure where the average part comes in, as there is only 1 value in consideration.
If someone could clarify this, I would appreciate it.
I looked through some of the HW's and not everyone is dealing with the ambiguity that exists in this homework. This is real life - often times data is not uniform. How is manager supposed to know what TBA will be working on a project means? And what does it mean to list the average cost of a project - what would be the most useful? Do you think your interface could help explain how your queries are working. Nobody has a guide, user manual or explanation of their queries - I think most of you are missing the point because you are being so "technical".
