Here are the directions for your test!
- You get two attempts on the final, and even though the first attempt will be viewable after you complete it, I will have to manually grade the essay portion so you will not know how you did on this part on either attempt.
- I will make the exam available for the entire week and I have it set in Blackboard.
- Most complete the exam in 1
hour to 1 ½ hours, but plan your time and how you will use it carefully.
There are 5 sections to the exam: an essay portion with 3 questions;
and computational sections on z-test, independent means t-test,
dependent means t-test, Chi-square, and Analysis of Variance.
- You may use the table of Area
Under the Curve, student’s
t Distribution Table,
Chi Square Table,
Table F,
your calculator, and scratch paper only. No notes, no books, only
what I have listed, that is all you will really need as calculations
are kept very simple and I do provide the formulas on the exam.
- WARNING!
Once you are in the test
in Blackboard,
whatever you do, do NOT hit the back button on the browser. Do
not worry when you hit the finish button, it may take some time to process,
but it will.
- Remember, once you hit the finish
button your exam will be graded and placed into the grade book for you
to view. A portion, however, will not be graded (the open-ended
questions at the top) until I go back in and manually score them.
When I am done, you will see your grade change in the grade book.
I usually have them completed the following day by the end of the afternoon
