Principles of Statistics Study & Vent!!!

[kimaya24]

The last couple of weeks I've been studying for the Principles of Statistics DSST & I'm scheduled to take it this Friday. I've used the statistics feedback forum to give me motivation when I get discouraged, but I've read those posts about 100 times now so I thought it would be neat to have a place where anyone that's studying for statistics (or already taken it) can share how their progress is going, neat stat sites they've found, share their "aha" moments/ study tips, ask questions, or just random thoughts of how annoying, irritating, frustrating their study is going, etc. Anything about the statistics exam in general that can't go in the Specific Feedback Forum

Sooooo, like I said I started studying last week, but it seems like I wasted the whole time learning standard deviation and variance! This whole week I've been a nervous wreck feeling like I am TOTALLY unprepared & that I should reschedule the test, but in just the last couple days I'm getting more and more confident & ready to take this one on & get it over with (amazing how things seem to come together at the last minute...unless I end up failing lol!). Anyway, I took a Peterson test and scored a 48% The DSST scoring site http://www.getcollegecredit.com/pdfs/exam-scoring.pdf says you need 42% - 46% to pass.. So I decided to do some "statistics" on the answers I got right/ wrong on the practice (which I hadn't covered a lot of the material yet & wasn't trying very hard, mostly guessing). Here's what I came up with:

Questions I got right where I was:
100% Sure..........................................................19
Pretty sure/ educated guess.................................. 10
Purely lucky guess................................................16

Questions I got wrong but should have gotten right.....9
(didn't pay attention to the question or too lazy to work the problem)
TOTAL...................................................................54

What does all this mean? Well, my null hypothesis of the correlation between the standard deviation and the coefficiency of my guessing ability taking into account the empircal rule that I have a terrible memory multiplied by the fact that I spend more time screwing around in the IC forum than I do actually studying, I can say with a 95% confidence level that the relative frequency of the probability that I need to study some more is about 100% (+/- 5% margin of error). Hahaha...I had to do it

Seriously though, based on this I think I could possibly squeak by with a pass, but my plan is to keep studying, take another test and try to increase the number that I'm sure on and pretty sure on to 30 each and up my overal score to at least 60 on 2 tests. If I do that, I'm gonna go for it on Friday....please pray for me!!

I really hate studying for a subject I don't like.. it's such torture!

I bet that with all of the effort you're putting into it, you will pass. I will keep my fingers crossed for you so that you can get it done and move on!

Thanks, I understand the basics of statistics, but then when they get into those long drawn out formulas my mind just goes blank!! I'm ready to be done with this one for sure!

That's what I keep telling myself I've got all these terms floating around in my head, they're the last thing I think of when I got to bed, the first thing that comes to mind when I wake up, and even in my dreams!!! They're haunting me LOL!!

If you'd like to roll the dice <grin> you can pay $20 and take the ALEKS statistics assessment. It's open book and untimed (no pressure!). If you score 70% or higher you'll get the credit without having to take the DSST. Just an idea

I've seen people talk about ALEKS, but I don't really know what it is, I thought it was another test like DSST/ CLEP??? Does a college have to accept ALEKS for you to get credit? Because I go to Liberty University & I've never seen anything about them accepting ALEKS.

Short answer - If they accept anything ACE accredited, then they'll except ALEKS. You receive credit from ALEKS by having you work transcribed through ACE (American Counsel on Education).

Long (and Politically Correct) Answer - I have no idea. Better check your school.

Thanks! I'll definately ask

Okay, now I'm going to do a little venting on this frustrating subject!!

So, I'm reading the Idiot's guide to statistics and it says that Alternative Hypothesis is denoted by H sub 1, THEN I read IC and it says it denoted by H sub A (which makes a heck of a lot more sense by the way). So, I get a third opinion from a handy site I found Statistics Tutorial: Notation and it says that it can be either one.

I have had to do this so many times for this test it's reeeaaaallly annoying! I mean, why can't they make it just one way? Geesh.
