Data, Ska Data
· You may work on this exam individually or in teams of up to three students, as long as each student on the team is dedicating full effort to it. I encourage you to work together on this one but no freeloaders.
*** Answer Key
***
Individual Exam 1:
· This exam is to be completed individually.
· I will send it to you via email.
· Normally, this would be a timed, in class exam with no notes but it is too tricky to pull this off with students in quarantine, etc., and I’m getting too nice in my old age. So, you can consult your notes, previous assignments and spreadsheets, etc. and there will be no time limit.
· There are multiple versions of this exam. Any evidence of cheating (the right answers for the wrong version) will be dealt with ruthlessly – don’t do it.
