I think that I do get the big picture. I am able to get through most of the steps until it comes to the p-value and the final sentence. I can't really describe what the p-value is because I don't really understand it. Also, I need some clarification on how to make the "decision". That was a really long lesson... I started spacing out at the end. 8D
Hee hee, I have to say I agree with Amanda, it waaaaaaaaaaaas a long lesson. Not sure if I get the entire picture, but I think I get a pretty good view of it.
Um, I'm not positive but I think a p-value is how probable it is to see our hypothesis proved at least as true as the given hypothesis (not sure if I phrased this right, but it made sense in my head). Kinda like we have to prove that the event is at least as "guilty" as we think they are so we can prove we were right and that our hypothesis was correct (our hypothesis being "guilty"). We want the event to be "guilty" (which means an equal or more extreme p-value) to prove that it is true.
I really don't understnd what a p-value is. I tried to find it for problem 13 and i didn't get anywhere close. Leave a hint if you know how to do it.thanks
I think that i get the big picture, but i'm getting confused on some of the steps. i'm probably wrong cause i'm not really sure, but i think the p-value is the probability that our answer is around the same as Ho, given that it was true.?
Yes, I mostly understand after quite a bit of studying. The p-value is a 'measuring stick' as to how surprised we are. It is the probability that the event happened by chance, or, more specifically, the probability that the event could occur if our Ho were correct.
I'm still confused but my understanding of the P-value so far is that it closely shows how likely or unlikely the hypothesis is. If the value is really low and "surprises" us then we know the event is too unlikely to be cuased by natural variation? Am I close?
I understand the steps for the new types of problems and and begining to understand p-vaule. The example of using guilty and not guilty really helped me to understand the problems more but I think I need as little more practice and clarification on the ending sentance and tying it all together... It was a lot to take in for one class
I think i understand the big picture. We are using the best of our statistical abilities to disprove, or prove, statements. I believe the p-value is the probability that statement occured. This helps us to determine if, say, a product is truly working, or only seems to be working because of natural variation.
hmmm. i hope thats right! im so sleepy and i didnt even get a chance to attempt the homework. I hope quiz isn't too terrible! saa every one tom-... today! gosh.
The p-value is the value that we compare against alpha to see if our results are due to natural variation or if there is an underlying cause!!!!!!!!!!!
I understood the lesson last class for the most part. I'm not sure I understand quite everything though. P-value is the value of which you base whether or not you accept the original hypothesis or reject it.
umm..i kinda get the big picture..but i still get confused with the steps and such...i still kinda dont get what the P-value is even though we discussed in class a few moments ago..=/..
I believe a p-value is essentially a number that can help determine whether or not one's hypothesis is valid or not. I still need a bit more clarification
uhh i get the big p[icture in class but once i leave ya...i forget :( jen has a bad memory! so the p-value...uhh i know the definition is the probablity that we see results at least as extreme as we got given Ho is true...so can someone help me interpret this like in "jen speak"
I understand the big picture but im not fully sure that i understand the P-value. I sorta understand it deals with the H0 and how correct it is or how true it is but i dont understand the math content.
Well after being in class off and on as well as taking the test this morning, I think I might get the big picture; however I will never know...
So P-value, I think is the probability of something more extreme than lets say correlation, either positive or negative? It is like: If my p-value is less than 0.05 (5%), my correlation would be greater than the threshold value, so my result would be statistically significant right?
I know I did bad on the test.... Don't judge me... :(

maybe... I guess I'll find out tomorrow!
See you all in class everyone!

El grande pictura: SI.
P-value: Well I'd like to say that I understand it, but I would be lying. It would be nice to have a recap in class.
I think that p-value suppoerts or rejects the hypothise. I think?
The p-value is the value that we compare against alpha to see if our results are due to natural variation or if there is an underlying cause!!!!!!!!!!!
the p value is what we use to see if we can reject or not reject Ho

A p-value is a value that we use in order to prove or disprove the original hypothisis Ha.
I am sort of getting the big picture. P-value is the value in which to prove or disprove a hypothesis.

A p-value is the evidence we have to suggest if Ho, your hypothesis, has validity to it. We are trying to prove or disprove a sampled probability.
Pvalue is basically the value we use to find out if we have enough evidence to reject H0.
P-value I think is pretty much like what everyone has said, it is the big picture in solveing for proving or disproving the hypothesis of Ho.
...this is LeAnna not Warda
A p-value helps us to know if we should or should not reject Ho.
hi mr quinn!!! just saying hi, even tho i already posted!!! hahahhahahahahhahahahah. stats, i miss kelsey! ; (
