NBC News Marist poll sample: Live telephone interviews 

“Adults 18 years of age and older residing in the state of Pennsylvania were contacted on landline or mobile numbers and interviewed in English by telephone using live interviewers. Mobile telephone numbers were randomly selected based upon a list of telephone exchanges from throughout the state of Pennsylvania from Survey Sampling International. The exchanges were selected to ensure that each region was represented in proportion to its population. Mobile phones are treated as individual devices. After validation of age, personal ownership, and non-business-use of the mobile phone, interviews are typically conducted with the person answering the phone. To increase coverage, this mobile sample was supplemented by respondents reached through random dialing of landline phone numbers from Survey Sampling International. Within each landline household, a single respondent is selected through a random selection process to increase the representativeness of traditionally under-covered survey populations. Assistance was provided by Luce Research and The Logit Group for data collection. The samples were then combined and balanced to reflect the 2016 American Community Survey 5-year estimates for age, gender, income, race, and region. Results are statistically significant within ±3.9 percentage points [for all adults]. There are 713 registered voters. The results for this subset are statistically significant within ±4.2 percentage points. The error margin was adjusted for sample weights and increases for cross-tabulations.”
