Re: math question verrrrrry off topic

The one I hate, and now say at every start up class, is the student that **emails** me and says, "Hey I missed class today, can you email me back what you talked about?" I told them I will NOT digest class on email. If that were the case, I would just email and not show up for class! And then there are those that ask for my Powerpoints--I say no because of copyright violations.

I have a strict attendance policy and elucidate it every semester on the syllabus, and still last semester I graded 6 students down out of ONE class of 16.

PS thanks again all for clarifying how unclear statistics can be :)

Well, let's just say I was a little late to class that day, and a little out of sorts when I got there. It might make a better story if I could remember what grade he got, but I don't. But since the class involved homework and written papers, which he hadn't done, and since I graded strictly on pre-designated points for the assignments, papers and tests, I can't imagine that he did very well at all.

Wow, that guy had the nerve to ask it. I know teachers/professors hate that
question even when someone ask it after missing JUST ONE class.

While we're way off topic, once when I was teaching
statistics, a guy appeared at my office door just as I was
going to the classroom to give the last lecture of the term,
and said, "I haven't come to class all term; have I missed
anything?"  True story.

Tonight I went to a meeting. I worked with university

students a lot.

Tonight I chatted to a young sophomore. He is really a smart guy.
During the
chat, I asked him how early did he have to go to school

(because it is

cold here in MI in the morning). He said it doesn't matter

because he

skipped most of his classes (he is an engineering student.


subjects are more standardized and "fixed" especially for
freshmen/sophomores so you can learn them yourself from

textbook and


Then he said, "for my 1st and 3rd semester I skipped almost all the
classes, and I got a GPA of 3.9. The 2nd semester I attended almost
all of my classes, and I got a GPA of 3.6; so my conclusion

is it is

better to skip classes."

Talk about making conclusion from statistical data, huh?   :-)

Hey Katharine,

I don't know-- maybe.  I honestly didn't read the other

answers.  :)

Hmm, I thought that's what we all already have said, isn't it?
That that theoretical probability (1/4x1/4x1/4) would

hold only if

assumptions were met,  and since assumptions are

obviously not met

(for example, judging is not a random lottery of course

but is done

on the basis of criteria, arbitrary or otherwise but

certainly not

random).  Also, no one has said whether the 600 entries

are 600 works

or 600 people; I was assuming that they are 600 works


fewer than 600 people, in other words people could submit

more than

one work, in which case, as I said, the number of works

submitted per

person would also have to be figured into the equation somehow.
Besides, if one person submits ten pieces and another

person submits

one, the ten pieces by the one person couldn't be considered
independent entries in the same way one of those ten could be
considered independent of the one from the other person, and
independence is also an assumption that must be met in order to
consider the probability of acceptance to be the same for all

Okay, Chris.  Here is it-- straight from my resident



If they were the only 3 people from that institution

who applied,

AND if judging was completely random, then the

probability of this

is roughly 1 in 64 (key word: roughly).  If more than

that applied

from this same institution, and only 3 got in, then the


will be more complex.

Hope that helps. :)

OK for you math people (Yves?):  If there is a show and 600
entries, and 150 are accepted, there is a 1 in 4 chance of
acceptance.  If 3 people from the same institution are


what percent chance is that--is it 1/4 x 1/4 x 1/4 or a

1.5% chance

or is it a more complex formula?
