In-Reply-To: A<483D2371.3050604@gmail.com> Content-Type: text/plain; charset="iso-8859-1" Marta is correct. The conversion from a t-score to a z-score is t=z*10 + 50. Conversions involving z-scores are special because the mean of a z-score is 0 and the SD is 1. The general formula for score conversion is: Snew = ((Xold - Mold)/SDold)*SDnew+Mnew Where: Snew= new score Xold = old score Mold = old mean SDold = old standard deviation SDnew = new standard deviation Mnew = new mean Good luck, Jodene -----Original Message----- From: SPSSX(r) Discussion [mailto:SPSSX-L@LISTSERV.UGA.EDU] On Behalf Of Marta García-Granero Sent: Wednesday, May 28, 2008 5:19 AM To: SPSSX-L@LISTSERV.UGA.EDU Subject: Re: syntax to create T-scores from z-scores? Hi Art I might be wrong, but I think that the conversion from Z scores to T scores is: Tscore=Zscore*10+50 Best regards, Marta > open a clean instance of SPSS. > cut, paste, and run the following syntax. > > data list list/id (f3), zscore(f4.2). > begin data. > 001 -3.00 > 002 -2.58 > 003 -1.96 > 004 -1.68 > 005 0.00 > 006 3.00 > 007 2.58 > 008 1.96 > 009 1.68 > 010 -2.00 > 011 -1.00 > 012 1.00 > 013 2.00 > end data. > sort cases by zscore. > numeric Tscore (f2). > compute Tscore = zscore +50 + (10*zscore). > list. > > Art Kendall > Social Research Consultants > Celebrating the 60th Anniversary of the UN's Universal Declaration of > Human Rights > > > edunbar@ucla.edu wrote: >> Dear List members, >> >> Okay I hate to ask, but having spent too much time trying to figue >> this out on my laptop, what is the syntax to create T-scores from >> z-scores? >> >> Much thanks, >> >> ed dunbar >> >> ===================== >> To manage your subscription to SPSSX-L, send a message to >> LISTSERV@LISTSERV.UGA.EDU (not to SPSSX-L), with no body text except the >> command.
