Methodology
The NBC News|SurveyMonkey Poll was conducted online from February 24, 2016 through February 25, 2016 among a national sample of 7,230 adults aged 18 and over including 6,433 who say they are registered to vote and 1,007 voters who say they are supporting Donald Trump in the Republican primary. Respondents for this survey were selected from the nearly three million people who take surveys on the SurveyMonkey platform each day. Data for this week has been weighted for age, race, sex, education, region, and voter registration status using the Census Bureau and Bureau of Labor Statistic’s Current Population Survey to reflect the demographic composition of the United States. Because the sample is based on those who initially self-selected for participation rather than a probability sample, no estimates of sampling error can be calculated. All surveys may be subject to multiple sources of error, including, but not limited to sampling error, coverage error, and measurement error. To assess the variability in the estimates and account for design effects, we create a bootstrap confidence interval to produce an error estimate. The bootstrap confidence interval for this survey is plus or minus 1.8 percentage points for the full sample and plus or minus 1.9 percentage points for registered voters. To calculate the bootstrap confidence interval we use the weighted data to generate 5000 independent samples and calculate the 95% confidence intervals for the weighted average. When analyzing the survey results and their accuracy, this error estimate should be taken into consideration in much the same way that analysis of probability polls takes into account the margin of sampling error.
