Your help filling-in the handful of¬†empty cells (flagged with¬†“?”), is appreciated.
The goal of this undertaking is to better understand¬†the correlation between the methodological choices an election¬†pollster makes and the results an election¬†pollster produces.
This chart permits an analysis of variables such as:¬†
- Significance, if any, of the length of field period.
- Significance, if any, of the proximity of poll release to election.
- Significance, if any, of the number of undecided voters.
- Significance, if any,¬†of the number of respondents interviewed.
- Significance, if any, of the source of the sample.
- Significance, if any, of the type of interviewing technique.
- Significance, if any, of the method of respondent selection within the household.
- Whether one error-measure produces a different “most accurate” pollster than an0ther.
- Whether one error-measure favors certain types of pollsters over others.
The results from the Florida Republican Primary, shown here,¬†are not intended to be illustrative of anything other than a high-profile contest in which a lot of pollsters released research during the 7 days immediately prior to the vote. Results from other primaries, to be released over the coming days, may show other pollster rankings.
