I was taking the last QR test from Achiever and noticed a P-value problem, which is weird. Are we supposed to know this on the real DAT?😕

Achiever's P-value

Where in achiever did you get this question from?
It's in exam 5, question # 30.
It's something you don't want to be ignorant of. I've heard of students getting not just one, but a couple of the P-value problems on the real exam. Pick up a stats book and spend some time reading what it is all about. It shouldn't be that difficult to comprehend.

I took DAT last year, back when achiever had 3 tests. There was no question about p-value. But i was hit with a p-value question on my DAT. I think i got it right, but that was thanks to 2 years of Stats course i took in undergrad.
So to answer your question, it's safe to know and p-value questions do show up

Thanks for confirming that, wantVCUdental.
I am yet to look into this with a little more details. From the few pages on this topic I have browsed through, it is basically talking about how the null hypothesis is being rejected and accepted using the three methods -- left tailed, two-tailed, or right-tailed. Is there any expert out there who can input more help and insight here?
Thanks.
What about question 40 of test 4 on the 68-95-99.7 rule? Is this something that would be tested on the DAT as well?
This is a give away question on the DAT. You just need to know how to relate the sigmas (or standard deviations) with the data given on a normal distribution. Simple stuff, nothing complicated.

all I can remember of about pvalue is if its 0.05 or less reject the null hypothesis.
how to go about calculating it I have no clue.

my p-value question was straight forward.
do you accept or reject and the reason for it.

can anyone point out any website or source where p-value can be learned from? how the p-value is calculated

This wiki page is good for an overview of basic stats
funny... i did p values in physics lab years ago, totally forgot how to calculate it though... i dont remember it being hard though.
P-value questions on the DAT will be based more on your understanding and quick reasoning of a mini scenario. Calculation will be minimally involved, and definitely won't be as extensive and detailed as it would incur on an advanced physics lab having several other complicated steps like linear regression to come along with it.

Glad to know that it's going to be easy and straight forward, cuz the calculation really stinks.
