Thanks Jean. I'll take a look at this. Thankfully I know how to read Nemeth. I have just never encountered these particular symbols before. Algebra was simple enough. Stats is killing me, especially since our book's explanations of new symbols is a bit lacking to say the least. Honestly, all of us (sighted or not) get more out of what the professor says than the book when it comes to things like this. -Alyssa -----Original Message----- From: duxuser-bounce@xxxxxxxxxxxxx [mailto:duxuser-bounce@xxxxxxxxxxxxx] On Behalf Of Jean Menzies Sent: Thursday, October 13, 2011 2:10 PM To: duxuser@xxxxxxxxxxxxx Subject: [duxuser] Re: Nemeth Question Hi Alyssa, Your description of what you are seeing in braille is correct for the representation of sigma sub cap M. I know that isn't encouraging when you perhaps don't know how to read Nemeth. I would recommend the book from the American Printing House for the Blind called Introduction to Braille Mathematics by Helen Roberts, Bernard M. Krebs and Barbara Taffet. It is much easier to work with than the actual Nemeth Code book. In braille, it is four volmes, and has chapters broken down into various topics. Example, you can easily find the sections on Greek letters, subscript, superscript, etc. This is actually a companion book for the Nemeth Code rule book, and is part of the Nemeth certification course. You should be able to find the sections that apply to what you need, and read the parts you need. Good luck.

After looking at the link you sent as well as the Nemeth code book, I'm still scratching my head. Granted, I only skimmed through the material, but I still do not see exactly what I am looking for. I also called NBP, but their reference sheets don't cover this either. I'm going to try to paste something in below that my professor gave us to see if this gives you any more specific idea of what I am looking for, but before I do that, let me try to further clarify what I am seeing in the book. For example, what he is referring to in class as sigma sub-M is supposed to stand for standard error. In braille, I am seeing the Greek letter sign of dots 4-6, the letter s, followed by dots 5-6, a capital sign and the letter m. There is another type of standard error for a sample, but this one does not have the Greek letter indicator before it. So basically what I am looking for is a sheet that describes all of these oddities in a nice, easy-to-read way. If what I am attempting to paste from our stats site works well, the below information is similar to what I want to have in braille. I'm going to try to get this particular sheet transcribed, but the problem I have is that there isn't anyone at the university who knows the Nemeth code. My book was sent off to transcribers in California, so it's rare that anything must be directly transcribed by university staff. I really appreciate any help on this matter. Below are the following symbols and their meaning. N = the number of observations (participants or objects) in a sample (sample size) X = a single value on a distribution of scores or means Σ = tells us to add all the values that follow this symbol M = the average of observations in a sample SD = the standard deviation for a sample SD2 = the variance for a sample μ = the average of a population on a distribution of scores σ = the standard deviation for a population on a distribution of scores σ2= the variance for a population on a distribution of scores μM = the average of a population on a distribution of means σM = the standard deviation for a population on a distribution of means σ_M^2= the variance for a population on a distribution of means s = the estimated standard deviation for a population on a distribution of scores based on a sample s2= the estimated variance for a population on a distribution of scores based on a sample sM = the estimated standard deviation for a population on a distribution of means based on a sample s_M^2= the estimated variance for a population on a distribution of means based on a sample d = the effect size (difference between two population distributions) df = degrees of freedom (the number of values in a dataset that are free to vary) -Alyssa -----Original Message----- From: duxuser-bounce@xxxxxxxxxxxxx [mailto:duxuser-bounce@xxxxxxxxxxxxx] On Behalf Of David Holladay Sent: Thursday, October 13, 2011 11:56 AM To: duxuser@xxxxxxxxxxxxx Subject: [duxuser] Re: Nemeth Question Alyssa: I have a document (that is part of the MegaDots documentation) that is designed to help a Nemeth reader. It is on the Duxbury Web site: http://www.duxburysystems.com/documentation/megadots/fnemread.htm I hope this also proves useful. -- David Holladay Duxbury Systems At 12:53 PM 10/13/2011, you wrote: >Thanks guys.
