Using a BAII Calculator for Statistics

[kimaya24]

I had a feeling you were going to use it for multiple subjects. I find it easier to have at min two calcs on hand, a finance and a statistical. It will make your life so much easier. I learned early on when I got stuck during a test trying to make a calc work and ended up wasting precious time by doing the problem pen/paper.

Good luck on your exam!!

Me too! When I was taking Algebra I had like 3 or 4 I would use! Of course I have a 10-key desktop/ printing calculator for accounting, also a plain jane handheld, and a couple of different scientific ones...one I liked because it had 2 lines and was good for fractions, but I didn't know how to use many of the functions on that one & it always gives the answer in fractions which isn't always what I wanted; the other one I could do functions on and it gave regular answers!!

I hadn't used them in a long time and one of my scientific ones doesn't work anymore and my plain one calculated 0-10 as 10!?! Soooo, I figure this is the perfect time to restock my calculator supply lol!!

Can only contribute regarding instructions on how to use this. It was required some years ago for Intermediate Algebra and, as you mentioned, useless instructions came with it.

I did a simple Google search with TI BA II and put in the words Power Point in the search engine. Believe it or not I found some instructions in general but also a nice and thorough PP created by a middle or high school teacher. More than enough to practice and feel comfortable in the test. Sorry, but did not keep the page in favorites.

Thank the Lord, the test is over. I've taken several CLEP and Dantes tests, but this is the only one I really, really panicked about. I'm in the BSN nursing program and I knew passing this exam would save me about $4000 and 16 weeks of additional school. I am grateful for InstantCert because the test questions did boast my confidence level. I'd purchased several books- Idiiot's guide to Statistics, Statistics for Dummies, the Cliff Notes for Statistics, etc...
I also bought a 30X IIS calculator and downloaded a manual about how to use it. After viewing the manual several times I was able to learn how to use it. It only cost $15. However, the exam I took provided an on line calculator and we were not supposed to use another one. But... as others had reported, there were very few questions requiring extensive calculations. The most questions asked requiring math were about finding the standard deviations. They did not ask a lot of questions about binomials, of which I was very grateful!!!! There were questions about means and medium, and one about mode. Also, identifying a few formulas: like variance and standard error. A few about degrees of freedom, z and t tables. They provided the tables at the very beginning but never looked at them again. I was concerned in the beginning with the slow speed of loading a few questions and the time limit of two hours. So, I finished with 7 minutes after answering the last questions. But, by that time, I was such a nervous and frustrated wreck, I doubt I could have reviewed them anyway. I wanted done!!!! They asked one question about descriptive statistics and used numbers versus adjectives in the answer. They asked about: R and L skewed bell curve with means/ medium higher or lower: a LOT about regression and correlation, bimodel curve, positive and negative relationship with scatter plots ( several of these), margin of error, null and alternative hypothesis, confidence levels, alpha and two tailed tests, don't forget to square the numbers, chi square,paired t test,p values, and type I and II errors.

They truly must have been generous with a curve as I passed it by much more than I thought I should have. Soooooo glad it's over. Good luck. Like others have said, just have a general understanding of definitions and "why" and you should do well.

Congrats on passing!! I ordered the idiot's guide and the statistics workbook too. I wasn't going to, but I'm nervous as well. I don't like to overstudy, but I want to have a couple different sources on this one in case I understand one better and also I would like to get plenty of practice on the problems. I want to be 100% sure that I'm going to pass...the thought of having to take this class is nauseating!!
