July 11, 2019 -- WebMD’s survey was completed by 1,084 respondents from May 16 to May 19, 2019, drawn from AmeriSpeak, a probability-based panel designed to represent the U.S. household population. The margin of error for a statistic at 50% is +/- 2.98 percentage points at the 95% confidence level for the entire sample of 1,084 respondents. Statistics for subgroups of the sample have larger margins of error, as do statistics greater or less than 50%. Most questions in the survey were completed by a subgroup of 780 (755 weighted) respondents who had experienced a grief event in the past 3 years.
Funded and operated by NORC at the University of Chicago, AmeriSpeak is a probability-based panel designed to represent the U.S. household population. Randomly selected U.S. households are sampled with a known, non-zero probability of selection from the NORC National Sample Frame, and then contacted by U.S. mail, email, telephone, and field interviewers (face to face). AmeriSpeak panelists participate in NORC studies or studies conducted by NORC on behalf of government agencies, academic researchers, and media and commercial organizations. NORC at the University of Chicago is an independent research institution.
