Professor of Public Administration; Director of the Survey Research Laboratory
Whether it was exit polls, phone polls, or unscientific web polls, the 2016 presidential election proved that not all public opinion research is equal.
Survey expert Tim Johnson, director of the Survey Research Laboratory, says methodology, sampling, transparency and margin of error are among the attributes that distinguish the quality of surveys and resulting data.
He was named a fellow of the American Statistical Association for his work exploring cross-cultural issues in survey research, particularly as it relates to disadvantaged population’s health behaviors. Part of his investigation in this area has involved cultural variability in the processing of survey questions, a factor that contributes to nonresponse and measurement error.
Johnson, who also serves as president of the American Association for Public Opinion Research, can discuss best practices for surveys and assess methods related to designing, conducting and analyzing public opinion polls.
