It's so dang hard, and I am practically failing the class.  Oh, it's business stats...standard deviation, hypothesis testing, contingency tables...blah, blah, blah.

Actually, statistics books are notorious for being written in such a way that no normal human can understand them. The trick, generally, is trying to find a way to relate the problems to something you're interested in. For example, if you like basketball: one possible sampling distribution would be the number of free throws individual players make over a season. You could take a sample of, say, 10 of the players and find the mean and standard deviation. You could compute a 95% confidence interval with that information, which would allow you to say that you're 95% confident that the average number of free throws made by NBA players in a season will be between this number and that number. You could find the probability that a given player would make at least a certain number of free throws in a season by finding the z-score and looking it up on the normal probability distribution table, etc. If you're really struggling with the terminology, I recommend visiting your math help center on campus (most of them have one), or contacting a tutor.

I don't know of any people who tutor online.\n\nThere are a number of good free statistics textbooks.  See the link.\n\nYou may also find it helpful to visit the library and read what different textbooks have to say about things that are stumping you.

Have you considered finding a tutor or speaking with the professor or TA about ways to help yourself through the class?  Once you grasp a few key concepts, biochem isn't all that hard of a class.  It's just getting to that point that's the challenge.  Good luck.

I was a Psychology major and was AWFUL at math.  But I passed regular statistics w/ a B.  Then when I got to grad school & had to take advanced statistics I flunked the course 3 times & then gave up.  I never got my masters all because of that ONE f*cking class.  I hope you have better luck than I did.

Your going to compare your mean with the population mean and see if your class really better than the average of the population.\nHo: u = xbar\nHa: u < xbar\n\nalpha = 0.10\none tailed test (of course)\ntherefore: z(table) = -1.28 (i'm not sure)\n\nuse z test since you know the population standard deviation.\n\nz = (x - u)/o/sqrt of n\n\nthat's it.\n\ngood luck

This sounds like homework to me.  Please tell me it's not: I'd be horrified to know there are still schools that corrupt a student's brain by not teaching metrics.

Thought I already knew everything! You go to the top of the class, while i hang my head in shame :(

You should have learned the material in class so you wouldn't have to cram and do last minute study. Have a couple of beers.

You should have course notes, and spend time re writing out all the noted you made in the classes. They aren't easy, IMO. It took me two tries on each one.\n\n\nTry www.examinit.com, they have cheap (not free) practice tests, which should increase your chance of passing.\n\nGood luck!

i still gota bunch of math<:( grrr....

you need to do a bunch of problems to get comfortable with formulas and with the math.  just do all the problems in the back of the book and you'll be fine.  if you're still having problems go see your professor or TA

Ick! This sounds too much like homework.

You've got to be kidding.  This is like a whole semester test covering the senses.  You need to start reading your textbook if you hope to get through this.

just take the course, business math and whatever foundation of math  it requires is easy stuff, stats and algebra (how can you be a businness person anyways if you cant do simple aritmatic and math). I hate math and i had to take 2 years of calculus for my major, that was a biatch. Anything that aint calc is easy.
