I recently rec'd a PM concerning the Statistics program through ALEK's. I realize this is common sense material for a lot of you out there but for some of us (non algebra, stats type people), here is some info that might be of value........
First, the program Algebrator works well in the beginning, but you have to pay for that. Here are some sites that helped me w/some of the problems:
QuickMath Automatic Math Solutions
Math.com Calculators and Tools
Statistics Index
Cumulative Normal Distribution: Probability Calculator
WebMath - Solve Your Math Problem
Find Equation Of A Line
Online Math Calculators and Solvers
Online Statistics Calculator, basic math statistics, Tutorial
Also, Math Help Forum is a good find, it is set up like InstantCert, you ask a question and after awhile, you normally get a reply. I've only used it on a few occasions near the end because I want to get this misery over. As for the ALEK's calculator, get familiar with the keys near the top. They will do the calculations for you. You plug in the data and hit = and you get your answer. Some problems have a LOT of numbers to add in order to figure the problem. The quickest way is to highlight the numbers on the screen and hit whichever button you need and voila, there is your answer. For instance, if you have 20 numbers and you want the sum, highlight those 20 numbers and hit the button that says SUM (right below the Store button). If you want the Standard Deviation, do the same and hit the small s button. The x w/the line over it gives you the sample mean. This will save you a ton of time. I just found this out and I'm at 70%, 56 BLUE and 14% GREEN. The formulas are also in the calculator, just plug them in and hit =. If your very weak at algebra and no experience at all w/Stats, good luck. If this is the case, my STRONG advice is if you don't know the problem, print a copy of it. I also highly suggest that you look for "KEY" words such as more than, less than, equal to, etc, because each has a certain way to do the formula. I would print a copy of each for future reference (meaning assessments). If you have only a copy that says more than and during your assessment you get a question that says less than, that may make you miss the question if you don't know how to manipulate the data. SO..... I would print copies when you get further along with the course, it may save you a big headache later. The key is to do as best as you can on the assessments. The more questions you miss on those, the slower your progress. Some may feel using calculators is cheating, I look at them as virtual tutors. For me, all I wanted was exposure to Statistics. If you plan on going into an MBA program, my belief is you better know the formula's or you will run into big trouble with the quantitative sections of your MBA, really any quantitative sections of any grad degree. In hindsight, I was guilty of rushing to get done w/out learning the calculator, a critical error on my part. Don't make the same mistake. Happy Hunting!
