Creating Web-based Surveys with Qualtrics

Qualtrics offers a way to create complex surveys without complicated programming or coding.  It offers survey design functionality that is more extensive than that offered by Survey Monkey.  Qualtrics offers an extensive library of surveys and options for encryption and anonymity. Qualtrics also offers foreign language functionality. Working within pre-defined templates, you can use many different types of questions, including text, multiple checkboxes, sliders, single-answer radio buttons, Likert scales.  Qualtrics also offers extensive branching functionality. Once the survey is completed, data can be downloaded into a format that can be used with Excel, Stata, SPSS, or other analysis programs.

This tutorial will also include a section on research protections and informed consent with respect to online survey development, distribution, and analysis. BC’s School of Arts & Sciences, CSON, CSOM, LSOE, and GSWW have purchased annual Qualtrics licenses that are available for use by faculty, staff, and students in those schools.  People not in these schools are also welcome to attend this tutorial. Those community members not in those schools may register for a limited free Qualtrics account at qualtrics.com. They may also obtain free access to Qualtrics online tutorials and help articles. It is recommended that you contact your school (A&S (researchservices@bc.edu), CSON (maria.vitone@bc.edu), CSOM, (researchservices@bc.edu) or GSSW (rita.vatcher.1@bc.edu) to obtain a Qualtrics account prior to the tutorial.
