Math 148 Announcements

Date posted   Message
12/19/2017 I have uploaded your adjusted total points and the resulting letter grade to Blackboard. They were "rolled" into the Office of Records database yesterday but it may take a few weeks until they show up on your temporary transcripts.
The column that lists your adjusted total points is displayed immediately to the left of the one that contains the letter grade. It should be named "GrandTotAdj" for sections 1-4 and "Adjusted Grand Total" for sections 5-8. It is calculated as follows:
        sum of all 12 quizzes minus the worst two
    + sum of all 6 graded homeworks minus the worst one
    + points for all four exams
    + attendance points
    + 3 extra points
It will in general be less than the column that displays your totals because that one incorporates the points of all 12 quizzes and all 6 graded homework, but not the 3 extra points.
I awarded those 3 points so that there is noone who was missing 3 or less points to get to the next grade. Accordingly, do not ask me to find an extra couple of points to improve your grade. These three points already took care of it.
Happy Holidays to all of you -- Michael Fochler --
12/10/2017 a. Finals preparation aid: The Course Materials page now contains a document Finals prep sheet which contains a chapter by chapter breakdown of what you may skip for the final exam.
b. Format of the final: The final will be a full 120 minutes and many of the problems will be like what you saw on the midterms: some multiple choices and fill in the blanks, some free form answers, some lengthier computations. Whats different: There will be material from the later chapters 25, 26, 28 where you are given computer output and you must figure out what to do with it.
c. Except for the final, all your grades should now be on BB. If you have any issues, email your TA with me in the cc and ask to meet with her/him. Do so asap!
d. Be early: The finals are labeled with your name and you will lose points if you are too lazy to look for your seat and take someone elses final!
e. Bring your student IDs: We will make spot checks! Index cards are bigger than for the midterms: 8 x 5 inches. Don't turn them in with your final. You are not allowed to write with a pencil!
f. How to practice: I have said this many times: Best you take the fully worked examples of the text and try to solve them closed book. Also review the summaries.

9/1/2017 Homework 2 has been fixed: ch.3 exercises start at page 74, not on p.101!
8/31/2017 Homework 2 has been posted.
8/24/2017 Notes concerning the textbook: a. You CANNOT USE the book someone used in a previous semester because both Math 147 and Math 148 switched from the Freedman/Purves/Pisani book "Statistics" to the completely different DBV text.
b. The publisher of the DVB text will send me copies that I can give to the library. I'll make an announcement when that happens.
c. Do you need the access code? I stated in the syllabus that it's required, but I also stated that all homework that will potentially be graded can be done without a visit to the DVB website. However, you may achieve a lower grade because you miss out on the practice problems I post there. Moreover you won't be able to use StatCrunch. You spend so much money each semester that I think you are "penny wise and pound foolish".
Note that Pearson made a special price for the loose leaf version with MyStatLab access. Just buying that access code will cost you about half the price of the entire package.
8/21/2017 a. Homework 1 has been posted. b. Syllabus and course material page now have information about registering with the MyStatlab website (also called the DVB website). Once you have access to MyStatlab you can access homework "MATH-148-DVB-01" (optional) on that site. c. Blackboard ("MyCourses") has not yet been set up for Math 148. We only use Blackboard to post the grades you get on your exams, quizzes and homeworks and to provide a PDF version of the syllabus. in addition to the HTML version found on this website.
8/11/2017 Be sure to look at all tabs of this website and to install the material on the DVD that comes with the text!
