The question is:
What is a sampling distribution? Illustrate and discuss why it?s important to inferential statistics.

Can anyone give me an answer to this question? thanks

I'll offer my World of Warcraft Account to whoever answers my question. Thanks

Well, you're gonna have to try, you don't just get free answers :p Read the article and INFER from what you read. It's better to make a guess than to have no answer at all.

clue
it has to do with testing a hypothesis and the statistical significance of your outcome

"Illustrate and discuss" - no one speaks that way... it's definitely a homework problem. You've been pointed in the right direction; show us what you think and we'll help you if you're not on the right track.

Probabilistic inference is the term you want to google. Im sure your instructor has mentioned that sampling must be random to meet one criteria of a sufficient estimate. Think about that.

Dr P, yes people do speak that way with exams. I know i did when teaching UG stats. However, without attending lectures its tough to infer what the question was addressing. If i was answering this i would address the sufficient (power) and random avenues. Basically, if your sample is not random or sufficient your estimate is shit.

If it's a normal model, the mean of your sampling distribution is an unbiased indicator of the true population distribution. And I think it is the same case with the variance too.
So basically if these moments are unbiased indicators of the true population moments then you can use them to "infer" information about the population by looking at the distributions?

Here's what I came up with so far:

A distribution is a way to model cases of scenarios. A sampling distribution is the way that some data of that scenario is giving in a certain time. Using sampling distribution, you can infer and even predict future events.

You have to define the rigth amount of sample you need depending on the total population you're studying.

When inferring, you must know the error that you're sampling and define how much you can accept depending on the significance of the study.


man... my brain is fried after writing 27 page research paper, 5 page essay, studying for 4 finals.

People who took Statistics, can you help me? I am trying... but I don't think my answer is sufficient.

That's what I was thinking (nothing particular on account). If I knew stats I'd help teh guy out.
