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.

Safety Analysis

The topic of safety analysis is of interest to several programs here. A key reference is,

Leveson, N. G. (1995). Safeware: System Safety and Computers. Reading, MA: Addison-Wesley.

I teach this topic as it relates to software in CS5744 and CS6704.

We have a workshop series on software reuse and safety at ICSR.

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.
