A Pew Research Center experiment found several key areas where Web surveys produced different results than those conducted by phone.
From Telephone to the Web: The Challenge of Mode of Interview Effects in Public Opinion Polls

Demographer Conrad Hackett explains how he and his team put together our major new report and why it differs from past efforts to predict religious change.
Building Pew Research Center’s American Trends Panel
In early 2014, Pew Research Center set out to build a probability-based panel – the American Trends Panel – to supplement our traditional method of data collection in the U.S. – the random digit dial (RDD) telephone survey. Here’s how we built and managed the panel, and what we learned from it in 2014.
What we learned about surveying with mobile apps
No research has compared app-based surveys with polls administered via Web browsers. Our new, experimental work compares the results of these two modes.
U.S. Smartphone Use in 2015
Nearly two-thirds (64%) of Americans own a smartphone, up from 35% in 2011. Today, 19% rely to some extent on a smartphone for internet access, but connectivity for these users is frequently tenuous.
App vs. Web for Surveys of Smartphone Users
Pew Research Center methodologists examine the efficacy of intensive data collection with a probability-based panel and the differences in participation and responses when using a smartphone app as opposed to a web browser for a study of smartphone use.
The challenges of using Facebook for research
We wanted to analyze the role Facebook played as a means for people to hear about, discuss and share local news. But getting the data we needed wasn’t easy.
