Qualtrics is an online survey tool that is very popular with researchers because of the combination of power and ease of use. It has many tools for branching and randomization and can output data as a fully-labeled SPSS file (in addition to standard Excel and csv). If you do not know what software to use, you can contact the Digital Scholarship Center (DiSC) at firstname.lastname@example.org to discuss the various options.
George Mason University has a university-wide license for Qualtrics. All students, faculty, and staff are allowed an account, but access is managed locally (either school, department, center, or other unit). DiSC does not control or administer Qualtrics accounts or licenses.
