via Latest National Poll – Donald Trump Support Surpasses Hillary Clinton… — The Last Refuge

The Fox News Poll is conducted under the joint direction of Anderson Robbins Research (D) and Shaw & Company Research (R). The poll was conducted by telephone with live interviewers May 14-17, 2016, among a random national sample of 1,021 registered voters (RV).  

Results based on the full sample have a margin of sampling error of plus or minus three percentage points.

[Not Yet Released] Additional interviews were conducted among 886 randomly selected Latinos.  These interviews were done to allow analysis of the subgroup, and are weighted so Latinos are not overrepresented in the overall national sample.  The total Latino sample is made up of 76 interviews conducted as part of the base national sample and 810 additional interviews from a Latino voter list developed from previously conducted national random digit dial surveys.  Oversample interviews were conducted by bi-lingual interviewers.   Results based on the Latino oversample have a margin of sampling error of plus or minus 3.5 percentage points.

Landline (508) and cellphone (513) telephone numbers were randomly selected for inclusion in the survey using a probability proportionate to size method, which means phone numbers for each state are proportional to the number of voters in each state.  

The base sample included 513 cellphone interviews and the Latino oversample included 498.  Fieldwork conducted by Braun Research, Inc. of Princeton, NJ. Results are of registered voters, unless otherwise noted.
