Longitudinal Surveys in Qualtrics
We’ll be using embedded data, authenticators, directories, and workflows to carry individual participant data from Prolific to Qualtrics, and from one Qualtrics survey to the next. This example will use Prolific to provide the participant ID, other panel services should work similarly. Initial opt-in survey Qualtrics surveys can read and…Read More
Protect Qualtrics Surveys from Bots
If you collect behavioral or market research observations online using Qualtrics surveys, data quality is a serious concern. Unlike in-person labs, paid data collection online is highly susceptible to fraud. In this post, we will revisit established best practices and adapt them to recent threats posed by Large Language Models…Read More
