The sample for this study was randomly drawn from Ipsos’ online panel (see link below for more info on “Access Panels and Recruitment”), partner online panel sources, and “river” sampling (see link below for more info on the Ipsos “Ampario Overview” sample method) and does not rely on a population frame in the traditional sense. Ipsos uses fixed sample targets, unique to each study, in drawing a sample. After a sample has been obtained from the Ipsos panel, Ipsos calibrates respondent characteristics to be representative of the population of each state using standard procedures such as raking-ratio adjustments. The source of these population targets is U.S. Census 2019 American Community Survey data. The sample drawn for this study reflects fixed sample targets on demographics. Posthoc weights were made to the population characteristics on gender, age, race/ethnicity, region, and education.
Statistical margins of error are not applicable to online non-probability polls. All sample surveys and polls may be subject to other sources of error, including, but not limited to coverage error and measurement error. Where figures do not sum to 100, this is due to the effects of rounding. The precision of Ipsos online polls is measured using a credibility interval. Ipsos calculates a design effect (DEFF) for each study based on the variation of the weights, following the formula of Kish (1965).
- For California, the poll has a credibility interval of plus or minus 3.0 percentage points for all respondents. This study had a credibility interval adjusted for design effect of the following (n=1,400, DEFF=1.5, adjusted Confidence Interval=+/4.5 percentage points). The poll also has a credibility interval of plus or minus 3.9 percentage points for respondents in the Los Angeles media market.
- For Florida, the poll has a credibility interval of plus or minus 2.6 percentage points for all respondents. This study had a credibility interval adjusted for design effect of the following (n=1,800, DEFF=1.5, adjusted Confidence Interval=+/-4.1 percentage points).
