About the study: ‘My’ media versus ‘the’ media

Methodology

This survey experiment was conducted by the Media Insight Project, an initiative of the American Press Institute (API) and The Associated Press-NORC Center for Public Affairs Research. The survey was conducted from March 8 through March 27, 2017. The survey was funded by API. Staff from API, NORC at the University of Chicago, and AP collaborated on all aspects of the study.

Data were collected using the AmeriSpeak Panel, which is NORC’s probability-based panel designed to be representative of the U.S. household population. During the initial recruitment phase of the panel, randomly selected U.S. households were sampled with a known, nonzero probability of selection from the NORC National Sample Frame and then contacted by U.S. mail, email, telephone, and field interviewers (face to face).

Interviews for this survey were conducted with adults age 18 and over, representing the 50 states and the District of Columbia. Panel members were randomly drawn from the AmeriSpeak Panel, and 2,036 completed the survey via the web and phone. There were 1,702 completed interviews via the web and 334 via the phone. The final stage completion rate is 35.6 percent, the weighted household panel response rate is 34.4 percent, and the weighted household panel retention rate is 94.7 percent, for a cumulative response rate of 11.6 percent.

The overall margin of sampling error is +/- 3.0 percentage points at the 95 percent confidence level, including the design effect. The margin of sampling error for the “news media” experimental group is +/- 4.2 percentage points while the margin of error for the “news media you use most often” experimental group is +/- 4.0 percentage points.

Respondents were offered a small monetary incentive ($2) for completing the survey. All interviews were conducted in English by professional interviewers, who were carefully trained on the specific survey for this study.

Once the sample was selected and fielded, and all the study data had been collected and made final, a poststratification process was used to adjust for any survey nonresponse as well as any noncoverage or under- and over-sampling resulting from the study-specific sample design. Poststratification variables included age, gender, Census region, race/ethnicity, and education. The weighted data, which reflect the U.S. population of adults age 18 and over, were used for all analyses.
