[Blindmath] AP Statistics

Hi Maria,

These are a couple of alternative strategies that I’ve discovered over the years.

While applying any particular formula, or theory, it is always important to remember the formula and the steps that are used to arrive at the final expression. The rest is just a matter of plugging in the values. If possible, your student can use simpler values for finding the standard deviation than the rest of the class in order to understand the method. After all, the object is to grasp the concept, and not to get into complicated calculations.

Although I like to use shortcut methods to reduce my dependency on a calculator, and also to keep my mind focused, this is not always possible. 
If she has access to internet in the class, then she could also use www.wolframalpha.com, which is far more powerful than any regular calculator.
See this web page for stats specific examples.
http://www.wolframalpha.com/examples/Statistics.html
The Math on the site is accessible with a screen reader, but if she prefers magnification, then it may or may not suit her.

As someone already said, you can also try Accessible Graphing Calculator (AGC) which is capable of evaluating and plotting expressions in Calculus, though I’m not sure if it can handle Statistics.

Excel is a great tool for managing questions that involve creation of huge tables, even if the stats based functions of Excel are not used.

Of course, she needs to know the different screens of whichever calculator is being used in the class in case her writer isn’t aware of the right way of working with one (I’m not sure what procedure is followed in US regarding this). But beyond understanding the basics of the calculator, I don’t think that she should focus too much on conforming to the class’s standard way of working.

Happy New Year
