clarification of previous comment

from:Bowen, Paul

to:Statistics

When you arrive at something by arithmetic, algebra, trigonometry, or calculus, you don't have to specify the reasons. But when you arrive at something on the basis of some Statistical principle, you should name that principle; or, on homework, you may say, "By the equation on page xxx".

Feb. 01, 2018

Giving reasons

from:Bowen, Paul

to:Statistics

In Math we don't just say things dogmatically, we give reasons. I'm going to say this again: if you give the right answer, without explaining *why* it is the right answer, you will receive NO CREDIT!

Jan. 31, 2018

Cancellation of assignment

from:Bowen, Paul

to:Statistics

Oops! I forgot that Wednesday 1/31 is AMC conference day! Also, I think that exercises 11.1 -- 5 (due that day) are too difficult. I am therefore cancelling that assignment. If you have done some of it, give what you have to me (or put it in my box, or send it to physis_asparagus@yahoo.com), and I will count it toward extra credit. I will create and distribute a substitute set of exercises.

We may be working on prep for AMC for awhile, so the substitute exercises will probably be due the first class after the AMC.

Jan. 31, 2018

PS to previous post

from:Bowen, Paul

to:Statistics

Also: I didn't have time, on Monday, to finish my lecture on Chapter 11. In my haste to get on with Chapter 11, I left it to you to read the rest. It occurs to me that this may have been unwise, and that after the AMC, I should continue my lectures on Chapter 11. What do you think?

Jan. 30, 2018

for Wednesday, 1/31

from:Bowen, Paul

to:Statistics

For wednesday, 1/31, hand in exercises 11.1 - 11.5.

Unscheduled vacations

from:Bowen, Paul

to:Statistics

The Schilling School has scheduled vacations. If a student's family wants to declare a vacation of their own, that is their privilege, but it does not absolve the student of homework or other responsibilities. Work should be sent to me at

physis_asparagus@yahoo.com

at or before the time due (class time on a date announced here). Note that it is is "physis", not "physics".

I don't penalize for absence, but I will penalize for failure to turn in work.

Jan. 29, 2018

Always give reasons

from:Bowen, Paul

to:Statistics

On tests, assignments, and the like, always give reasons for your answers!

Even if it is a yes-or-no question, don't just write one word. Show me that you know *why* the anwer is what it is!

In the future I will take off a point for answers without justifications.

Jan. 21, 2018

More about extra credit

from:Bowen, Paul

to:Statistics

If you do extra credit to make up for a bad grade, your resulting grade is determined as follows: Your grade on the make-up, expressed as a percentage, adds that percentage of the difference of your original grade and one hundred to your original grade. In other words, if your original grade is O, your grade on the extra credit is E, and your resulting grade is R, then R = O + (E/100)(100-O). For example, if you got a 40 on your first try, and then got a 50 on the extra credit, your resulting grade would be 40 +(50/100)(100-40) = 40 + 30 = 70.

This means that you have nothing to lose by doing the extra credit.
