How do you conduct a t- test for a set of matching pairs to find the t statistic, p value, and significance level? The matching pairs part is what's throwing me off.
oy this sounds familiar ....
a set of matching pairs, what is that?
For this example they're comparing two different drugs and the results.
http://stattrek.com/statistics/dictionary.aspx?definition=matched-pairs_t-test im reading this to refresh anyting i might have lost thru the years
whats our x1 and x2 ?
this might be easier.
you lied!! that is definantly NOT easier :)
haha, I meant easier to see it for me to describe...lol I have the values i L1 and L2 in the calculator, but not sure where to go from there.
what are the numbers in the reference and generic columns relate to?
Those are the results from the different drugs. So I'm guessing those would be the x1 and x2?
so each group received the generic and the reference drugs; but at different times and such that yada yada ....
exactly
but what do the numbers themselves mean?
The absorption of the drug in the blood
absoprtion extent = 4567 ....
so they are differing absorption thingys
right.
and youve created 2 separate lists on your ti83 or similar contraption so far
so far yes. I feel like I need to subtract one from the other though. I'm just not sure on that.
yes, L1-L2 will give us the required x1-x2 parts to distribute into a curve
L1-L2 = d then the mean of d and its associated sds and variances and curvilinear contraptions can be assessed
alright. do I need to subtract them separately? or could I do the total of L1-total of L2?
you want to so: sub1 : L1 - L2 = d1 sub2 : L1 - L2 = d2 etc ..... this way you have a running tabulation of effects for each random variable presented
so separatley is what ive got in mind
okay. Let me do that real quick.
whew. okay, got that done.
now with the new stuff in "d" as im calling it; we can construct a distribution and ints graph to perform calculations on
ok, so put the new list in the calc. then go from there?
yes, then we can test hypothesises and the normal day to day unpaired situations
Okay, I have it in. So I guess I need to find the μ ?
yes
http://stattrek.com/hypothesis-test/paired-means.aspx this page actually has a good working example that you can follow that parallels yours i believe
Great. Thank you!
yw, and good luck with it :)
Lol I think I got this one. We'll see about the rest of the course. :p
