Math 147B Announcements

5/13/2023 a. Your letter grade is computed according to the Spreadsheet math147B-grades-examples.xlsx. That link can also be found on the course materials page. You can figure out what that grade will be according to the following explanations:
QSum = sum of all 12 quizzes
QuizAdj = sum of best 10 quizzes
  • Examples:
    • User Charlie loses zero because two lowest quizzes = 0 + 0 = 0
    • User Delta loses 10 because two lowest quizzes = 5 + 5 = 10
    • User India loses 20 because two lowest quizzes = 10 + 10 = 20
HwSum = sum of all 5 graded HW
HwAdj = sum of best 4 graded HW
  • Examples:
    • User Charlie loses 20 because lowest HW = 20
    • User Frances loses zero because lowest HW = 0
    • User Hotel loses 5 because lowest HW = 5
TotSum = sum of attendance + all major exams + all 12 quizzes + all 5 graded HW
TotAdj = sum of attendance + all major exams + best 10 quizzes + best 4 graded HW
  • Examples:
    • User Golf: Both figures are the same because zero points were lost on both quizzes and HW
    • User Frances: 10 points were subtracted because 5 + 5 points were lost on the lowest two quizzes.
Add-5: Boosts your score by 5 points. Explained further in item b below.
Grade: The letter grade you would have gotten if I had applied the grading scale displayed in the "Your Grade" section near the end of the syllabus to the points total in the TotAdj column of the spreadsheet. Instead:Grade+5: This will be your letter grade! It results from applying the grading scale displayed in the "Your Grade" section near the end of the syllabus to the points total in the TotAdj column of the spreadsheet.   • Examples: • If your TotAdj score is 690, then your Add5 score is 695, and you will receive a B. • If your TotAdj score is 695, then your Add5 score is 700, and you will receive a B+ rather than a B.
Thus, You can compute your letter grade as follows: Take one of the users, say, "Your data!!", and overwrite the columns G (attendance) through AB (Hw E) with your BS data. The spreadsheet will compute the other columns, including Grade+5, for you.
IMPORTANT: If you skipped a quiz or homework, do not leave the entyry blank, and ENTER ZERO instead. Otherwise, Excel will not correctly drop the lowest HW and or quizzes.
b. Instead of a curve: As I have explained in part a above, I have given everyone of you 5 additional points. This ensures that nobody missed the next better grade by five or less points.
Accordingly, I am not open to discussions about improving your grade because you only need two or three extra points.
c. You can find the anonymous grades for the final on the grades page.
d. It was my privilege to be your instructor. I hope that the grade you obtained is what you were looking for, and I wish you all a wonderful semester break, and all the best for your future -- Michael Fochler --

Starting with the third quiz and the second graded homework you miss, you will be given a makeup, or your TA will count the next assignment double if there is an excused absence.

1/24/2023   I have fixed the syllabus entry in the instructor's BrightSpace.
It erroneously referred to the course site of Math 454 - Financial Mathematics, the other course I am teaching this semester.
If you are/were trying to submit "Homework zero" about your math background, you probably looked at that wrong website.
If you did, please be sure to review the correct website for this course, to be found at
http://people.math.binghamton.edu/mfochler/math-147B-2023-02/html/math-147B-home.html.
Sorry for the confusion.
1/23/2023   Since it starts at noon, Math 147B class will be held today in LH 8 as usual!
1/21/2023   I finished last Friday ch.2.3, but HW 2 covers material through ch.2.4 (Center). This affects homework about medians and means of a histogram.
If you cannot handle those particular assignments yet then work on them after Monday's lecture.
1/19/2023   I have posted HW 2. Due next week according to TA rules.
1/16/2023   The home page now lists the discussion sections. Note that changes are possible if a TA has a scheduling conflict.
1/14/2023   The Topics column in the schedule page has been updated.
1/13/2023   Exam dates have been set and the schedule and home pages have been updated accordingly.
10/30/2022   a. Prospective Spring 2023 students: Be sure to look at all tabs of this website! This may help you understand how well this course will suit you.
b. Review Homework 1 (from Fall 2022) NOW! It will help you understand whether you need to do some self-study as far as the math is concerned!
