PRRI January 2017 Sports Survey
SummaryThe Public Religion Research Institute (PRRI) January 2017 Sports Survey studies the popularity of different sports in America and explores Americans' beliefs in the supernatural in sports. It asks about issues facing women in sports, such as interest in watching professional women's sports and the perceived abilities and efficacy of female coaches. Finally, the survey gauges attitudes toward athletes making public political statements.
The ARDA has added five additional variables to the original data set to enhance the users' experience on our site.
Data FileCases: 1013
Weight Variable: WEIGHT
The weighting is accomplished in two separate stages. The first stage of weighting corrects for different probabilities of selection associated with the number of adults in each household and each respondent's telephone usage patterns. In the second stage, sample demographics are balanced to match target population parameters for gender, age, education, race and Hispanic ethnicity, region (U.S. Census definitions), population density and telephone usage. The population density parameter was derived from Census 2010 data. The telephone usage parameter came from an analysis of the July-December 2015 National Health Interview Survey. All other weighting parameters are derived from an analysis of the U.S. Census Bureau's May 2016 Current Population Survey.
The sample weighting is accomplished using an iterative proportional fitting (IFP) process that simultaneously balances the distributions of all variables. Weights were trimmed to prevent individual interviews from having too much influence on the final results. The use of these weights in statistical analysis ensures that the demographic characteristics of the sample closely approximate the demographic characteristics of the target populations.

Original Survey (Instrument)PRRI January 2017 Sports Survey
Funded ByThe survey was made possible by a generous grant from the The Nathan Cummings Foundation.
Collection ProceduresData collection is based on stratified, single-stage, random-digit-dialing (RDD) sample of landline telephone households and randomly generated cell phone numbers. The sample is designed to represent the total U.S. adult population and includes respondents from all 50 states, including Hawaii and Alaska. The landline and cell phone samples are provided by Marketing Systems Group.
Sampling ProceduresThe survey was designed and conducted by PRRI. Results of the survey were based on bilingual (Spanish and English) RDD telephone interviews conducted between Jan. 18-22, 2017, by professional interviewers under the direction of SSRS. Interviews were conducted among a random sample of 1,013 adults 18 years of age or older living in the United States (604 respondents were interviewed on a cell phone). The selection of respondents within households was accomplished by randomly requesting to speak with the youngest adult male or female currently living in the household.
The margin of error for the survey is +/- 3.6 percentage points at the 95% level of confidence. The design effect for the survey is 1.4. In addition to sampling error, surveys also may be subject to error or bias due to question wording, context and
