CSTAT Fall 2025 Workshops

Introduction to Qualtrics (In Person)

November 7, 2025 1:00 - 4:00 pm

Presented by Dr. Wenjuan Ma, CSTAT - Farrall Agriculture Engineering Hall (FAE) 106

This workshop will introduce the use of Qualtrics. Qualtrics is an online platform often used for surveys, evaluations, and other purposes. The workshop covers the basics of Qualtrics. Participants will learn important features and concepts of Qualtrics and survey.

We will begin with an overview of the platform. Then, we will organize the workshop according to the stages of a project: design, implementation, and wrapping up. By using examples, we will demonstrate how to create questions, communicate to target audiences, visualize, and analyze the information after we collect it.
