“The NBC News|SurveyMonkey Weekly Election Tracking poll was conducted online August 1 through August 7, 2016 among a national sample of 11,480 adults who say they are registered to vote. Respondents for this non-probability survey were selected from the nearly three million people who take surveys on the SurveyMonkey platform each day. Results have an error estimate of plus or minus 1.2 percentage points. For full results and methodology, click here. “
Registered to vote. In other words, a worthless poll.
“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.”
Even acknowledges that the poll is skewed.
90 days out from an election only likely voters should be sampled.
