NC TraCS Data Science Seminar Series: Matching: An Observational Necessity

This seminar will provide a brief overview for why and how to match cohorts for use in studies using observational data, with a particular view to utilization of existing matching tools in Python and R.

Seminars in the NC TraCS Data Science Seminar Series will cover a range of topics related to health care data science, clinical data, data engineering, and working in these areas at UNC-Chapel Hill. These hybrid seminars will be held on the third Tuesday of each month from 12:30-1:30 p.m. in the NC TraCS suite on the 2nd floor of Brinkhous-Bullitt or via Zoom.

Qualtrics is a powerful browser-based web-survey tool. It is available to UNC Chapel Hill faculty, staff, and students, for UNC-related projects. Qualtrics allows users to build complex surveys, distribute them, and analyze the responses all from one place.

In this course, we will cover basic Qualtrics functions beginning with an overview of survey options and settings, followed by hands-on practice programming and distributing a survey and downloading results. We will program some of the most common question and response types, customize requirements and validation, and add display logic, skip logic, and basic branch logic in the “survey flow”. We will then create and upload a contact list and discuss advantages and disadvantages of distributing the survey with an anonymous link vs. the survey mailer. Finally, we will cover a basic overview of the Data & Analysis tab for viewing, editing, and exporting raw data into various formats including .csv, .tsv, .excel, and .spss. Other topics include project sharing/ collaboration, Groups and Libraries, and preventing fraudulent responses and bot activity.

This is an introductory course and will not cover use of the online analysis tools within Qualtrics. Please note, this is a hands-on course. All participants are required to create a Qualtrics account before the course.
