Statistics-Help

[sirjake]

My personal opinion about this test is that InstantCert IS enough to get a good score. That is disagreeing with others who have obtained a higher score, but I got a 65 myself, so that's something. Not a perfect score, mind you, but at least an A at Excelsior (55 or better). I did not have access to the Idiot's Guide. I did look through Statistics Demystified from my public library the night before the test and I think that it could have been very helpful had I had more time, but it really was too much to try to take in the night before.

Anyway, the long and the short of it is that I fully believe that if you did nothing but study IC *and* understand the material, you would have no problem passing this test.

Thanks SirJake. That is a little comforting actually. Although I will spend a little more time and study the Idiots Guide, just to be sure. Thank you for your input. Time to go study!

Instantcert is helping me learn Statistics quite well. I found an online resource that you may want to look at as well.

HyperStat Online: An Introductory Statistics Textbook and Online Tutorial for Help in Statistics Courses

I test in one week. :eek:

blackhawkguy, you don't need to read the entire idiot's guide. It goes way too deep for what you need. IC is good enough. If you don't understand something completely that is in IC, use the guide or something else for amplification. The last half of the idiot's guide is deeper than the exam goes.

Upgray,

So you think IC is enough as long as you know the info.?

Got my score back Tuesday.

68.

Like most on here it took me over 3.5 hours and I was in panic mode on some of the questions. If you want to pass this test you will want to get to the point of knowing everything on IC very very well.

IC does not go into some topics deep enough, null hypothisis is one of them. Study the logic of statistics, and how to use statistical language. Use at least one other book. I used a cheap book I borrowed from someone and it helped.

Don't take the test, or feedback on this forum for granted. I studied like crazy for this exam in order to pass, you should too.

enjoy.

I've been studying with the Idiot's Guide, and going through IC. I understand the concepts being asked on IC...

I still need to cover the "Regressions" section, but I don't think that'll be a problem.

I'm taking the CBT version of the exam through a local college. I used up all two hours the last Dantes exam I did on CBT... I'm hoping that IC doesn't steer me wrong. I just need a 48 to get credit... As long as I hit that, I don't care about much else! I'll post my comments afterwards.

Okay... I took this and finished with 15 minutes to spare. When I got to the end, I figured - it was either pass/fail. Fixing questions wouldn't do me any good. As I was going through the exam, I felt I forgot a lot of formulas I knew pretty well the night before...

I scored a 67.

There were several questions about chi-squared.
There were a BOATLOAD of null hypothesis questions.. and comparing two distributions and formulating a hypothesis.
There were a handful of probability questions

As stated before... the test is less about calculations and mostly on concepts. I had about 5-10 questions that would setup a problem... and you had to identify the formula to solve it. It sucked the first time, when I solved the question... and saw the answers they gave were formulas!

I took in a TI-36X and a TI-30X-A calculator. Either calculator would do fine on this exam. If you already have a TI-30X-A, just keep it. If you're buying a new calculator, go with the TI-36X. But for the 2 questions I got on correlations and y-intercepts, I didn't need the functions the TI-36X offered.

All in all, this is not a tough exam. If you study the Complete Idiot's Guide, know chapters 9+, and understand the concepts of probability. Use IC, because the style of the questions are very similar.
