Survey Tools

Survey Monkey http://www.surveymonkey.com/
Cost is reasonable; can create your online questionnaire for free and then pay for one month during data collection.
If you plan to use Survey Monkey for an electronic survey, be sure to include in your IRB application that you will have SurveyMonkey "enable the SSL" before data collection. In this way, the results you get will be truly anonymous and there will be no record kept of respondents’ IP addresses.

VT survey tool survey.vt.edu
Free for faculty and students. OK for short questionnaires where don’t need page-breaks or skip routines.

Blackboard learn.vt.edu - but this only works for VT PIDs

VT SONA system http://www.psyc.vt.edu/research/sona.html - used by the Psychology Dept. for for online research study participation.

JMP Statistical Software

JMP is also a software environment for statistical computing and graphics, brought by the SAS Institute Inc. It provides a great statistical interpretation to researchers, product innovators, and quality improvement managers.

The University has currently an agreement with SAS, so that JMP can be used by all faculty and graduate students through the Software Network. It is also available for Windows, Linux and MacOS.

We suggest that you use version 6.02 because version 7 will expire September 08.

R for Statistical Computing

R is a free software environment for statistical computing and graphics. It compiles and runs on a wide variety of UNIX platforms, Windows and MacOS.

A good introduction to R can be read from J. Verzani in Simple R: Using R for Introductory Statistics.

For a detailed description on how to read and write data, R Data Import/Export, by the R Development Core Team, can be read. Another good resource is Using R to Teach Econometrics, by J. Racine and R. J. Hyndman.
