This database of directory-listed numbers is then used to determine all active blocks – as we define it, contiguous groups of 100 phone numbers for which more than one residential number is listed. Our practice for ABC News is to develop a range of “likely voter” models, employing elements such as self-reported voter registration, intention to vote, attention to the race, past voting, age, respondents’ knowledge of their polling places and political party identification. However, an ABC-led study (Merkle, Langer, Cohen, Piekarski, Benford & Lambert, 2009, Public Opinion Quarterly) found that this “cleaning” process excludes respondents who have home-based business-listed phones and no other lines at home on which they take calls, creating 3 percent noncoverage of eligible households with no offsetting gains in productivity. Cell/landline proportions are per the most recent estimates from the U.S. Centers for Disease Control and Prevention’s National Health Interview Survey. In-state/out-of-state cell proportions are per Marken et al. All possible numbers in active blocks are added to the random digit database. And of those online polls, none are from some of the superior entities that do that methodology, like the Pew Research Center. A study published in 2000, “Consequences of Reducing Nonresponse in a National Telephone Survey” (Keeter, Miller, Kohut, Groves & Presser, POQ 64:125-48), found similar results in surveys with 61 and 36 percent response rates. ���k��k�>n��n�'���2�D~��[��7������>��hQ���>N�N�]�Pi���W�+��0?�1 ���|���+B���dž�0�뛇��M�ȗ�)�"��麈/���F�1ߢ��8 ����Q�@�� ����M�6�m����. That is not a good method of polling. The data then are weighted using demographic information from the U.S. Census and NHIS to adjust for variance from population values. From October 2008 to June 2015, data were post-stratified to Census region by sample type; rim weights then were calculated using Census parameters for age, race/ethnicity, sex and education. Proprietary research is not exempted. This increase prompted our decision to boost our proportion of cell phone interviews to 75 percent, improving the representativeness of our samples. Methodology Sample View help for Sample. It found a 51 percent approval rating on April 16, though the average approval rating for April 16 to April 18 was 48 percent. More than 25 years, 475 surveys, and 500,000 individual interviews later, the partnership has proved an enduring one. %PDF-1.7 Methodology This ABC News/Washington Post poll was conducted by landline and cellular telephone interviews Sept. 8-13, 2020, among random samples of 705 Minnesota registered voters, including 615 likely voters; and 702 Wisconsin registered voters, including 605 likely voters. ABC/Post poll design effects averaged 1.25 in 2016, rising to an average of 1.38 in 2019. Interviews are conducted via a computer-assisted telephone interviewing (CATI) system. As a result of this evaluation, we do not exclude listed business numbers from our landline sample, with the exception of those in business-only blocks or exchanges. Cell-only respondents are screened for age eligibility (18+). ABC News/The Washington Post Gun Poll, April 2007. On the other hand, surveys that, for instance, do no within-household selection, or use listed-only samples, will increase their cooperation or contact rates (and therefore response rates), but at the expense of random selection or population coverage. The final ABC News/Washington Post poll had him winning in the suburbs by 5 points. The surveys were designed by Langer Research Associates for ABC News in conjunction with The Washington Post, with sampling, fieldwork and data processing by Abt Associates. Sampling error can be calculated when probability sampling methods, such as those described here, are employed, using the standard formula (at the 95 percent confidence level) of (SQRT(.25/sample size))*1.96, plus adjustment for design effects. We do accept some probability-based surveys that do not meet our own methodological standards – in terms of within-household respondent selection, for example – but may recommend cautious use of such data, with qualifying language. Cell sample respondents’ place of residence is checked and their Census region adjusted accordingly if necessary. As a result, in July 2015 we adopted an overlapping dual frame sample design, in which cell phone respondents are interviewed regardless of whether or not they also have a landline. The ABC News/Washington Post poll also found that 59 percent of Americans would prefer to vote in person in this year’s election, while 38 percent would prefer to vote by mail. Interviews are carried out by professional live interviewers employed by Abt Associates, working from Abt call centers in Fort Myers, Florida; Charleston, West Virginia; and McAllen, Texas; or from their homes, under full remote supervision. Up to its final disposition, each sampled phone number receives a minimum of five dialings, at different times of day on different days. Response rates are calculated using sample dispositions. Pre-election polls make their best estimate of this population. The database is sorted by county code, carrier name and 100-block. Weights may include average partisan self-identification in current and recent ABC/Post data, based on a standardized rule. It’s worth noting that the ABC News/Washington Post survey comes as a series of other key polls were released on Sunday, indicating Biden’s narrow lead over Trump nationally and in battleground states, even though some state races remain very close.. TOPLINE & METHODOLOGY About the Study This ABC News/Ipsos poll was conducted October 23 to October 24, 2020 by Ipsos using the probability-based KnowledgePanel®. He also does not point out that most of the other major polls show that the vast majority of the American people HATE Obamacare. For the cell phone sample, SSI begins with a monthly listing of every existing telephone area code and exchange. New polls, polling analysis and poll information from the Post. Non-probability, self-selected or so-called “convenience” samples, including internet opt-in, e-mail, “blast fax,” call-in, street intercept and non-probability mail-in samples do not meet our standards for validity and reliability, and we recommend against reporting them. ABC News/Washington Post Poll, March 1996. The design effect due to weighting describes the overall impact of sample weights and is used in calculating the survey’s margin of sampling error. In July 2015, post-stratification by sample type was discontinued and Census region and phone service (landline only, dual service and cell-only) were added to the rim weighting variables. ABC and The Washington Post direct the methodological approach to full-length ABC/Post polls in consultation with our field work provider for these surveys, Abt Associates of Rockville, MD. About half of these are pooled by their producers in contiguous groups of 10 100-block phone numbers, or 1,000-blocks, with information including whether each pooled 1,000-block does or does not include cell phone numbers, either solely or on a shared basis with landline numbers. |'��>����?s>����X׃������[�ܿ//�� ���2\�r3��-|(�-~�6I���k���_��~2)��~24R7T���#�~Sz0��a�� �#lS�;���b��t�YU�g,���`���J�E ��ű�ʳ%H�^®�f���������[�;���5�maX�����殿���{�2�q�Һ� ABC News and The Washington Post initiated their polling partnership on February 19, 1981, announcing an 18—month agreement to jointly produce news surveys on current issues and trends. Data are adjusted to account for the greater probability of respondents who have both a cell and landline phone, compared with those who are cell-only or landline-only. For exchanges or 1,000-blocks that have been classified by their carrier as providing both landline and wireless service, each 100-block is compared to the database of landline 100-blocks; 100-blocks that appear on the landline frame are removed from the wireless frame and 100-blocks with no directory-listed numbers are retained. By including business-listed numbers, for instance, we increase coverage yet decrease contact rates (and therefore overall response rates). METHODOLOGY – This ABC News/Washington Post poll was conducted by landline and cellular telephone May 25-28, 2020, in English and Spanish, among a random national sample of 1,001 adults. This evidence challenges the assumptions that response rates are a key indicator of survey quality.”. As far back as 1981, in “Questions & Answers in Attitude Surveys,” Schuman and Presser, describing two samples with different response rates but similar results, reported (p. 332), “Apparently the answers and associations we investigate are largely unrelated to factors affecting these response rate differences.”, Among many other sources, in "The Causes and Consequences of Response Rates in Surveys by the News Media and Government Contractor Survey Research Firms,” in Advances in Telephone Survey Methodology, Chapter 23, Wiley 2007), Holbrook, Krosnick and Pfent reported that “lower response rates seem not to substantially decrease demographic representativeness within the range we examined. Methodology Sample View help for Sample. Each 100-block is assigned to a county based on the billing coordinates of the exchange. 24/7 coverage of breaking news and live events. In addition to recommending against reporting surveys that do not meet appropriate standards for validity and reliability, we promote and strongly encourage the reporting of good-quality polls that break new ground in opinion research. Samples were composed as follows: Sample frames are sorted by state geopolitical regions. stream Methodology This ABC News/Washington Post poll was conducted by landline and cellular telephone May 25-28, 2020, in English and Spanish, among a random national sample of … Our recruitment process employs a scientifically developed addressed-based sampling methodology using the latest Delivery Sequence File of the USPS – a database with full coverage of all delivery points in the US.

Trump is the only one in the group to be seen unfavorably by most Americans, 56% in this poll, produced for ABC by Langer Research Associates.He's seen strongly unfavorably rather than strongly favorably by a 17-point margin, 46-29% -- about double the strongly negative margin for Biden, 8 points, 34-26%. Cell-only respondents are not offered compensation, but a reimbursement check is offered if use of minutes is raised as an objection. Yet actual voters are an unknown population – one that exists only on (or, with absentees, shortly before) Election Day. Households were selected by random-digit dialing. (See Langer, Public Perspective, May 2003. <> Abt SRBI’s professional interviewers, and their supervisors, are extensively trained in interviewing practices, including techniques designed to achieve the highest possible respondent cooperation. This poll is based on a nationally representative probability sample of 551 general population adults age 18 or older. Weights are trimmed to a range of 0.2 to 6.0, again as with ABC/Post national polls. Within households, the respondent selected was the adult living in the household who last had a birthday and who was home at the time of the interview. A survey’s response rates represents its contact rate (the number of households reached out of total telephone numbers dialed, excluding an estimate of nonworking and business numbers) multiplied by its cooperation rate (the number of individuals who complete interviews out of total households reached). This ABC News/Washington Post poll was conducted by landline and cellular telephone interviews Oct. 12-17, 2020 among a random sample of … We shifted this proportion to 75/25 percent in March 2020. 2009). 1 0 obj The latest ABC News/Washington Post tracking poll, released Thursday morning, Finds Hillary Clinton leading Donald Trump 47-44 percent in a four-day average among likely voters.

Cell respondents are screened for age 18+ and their state of residence is confirmed. Within households, the respondent selected was the adult living in the household who last had a birthday and who was at home at the time of the interview. SSI starts with a database of all listed landline telephone numbers, updated on a four- to six-week rolling basis, 25 percent of listings at a time. SEE: Cartoons on the 2020 Presidential Election ] For missing data, a weighting cell is set to 1% for respondents who did not answer a given question used in weighting, and the substantive categories are adjusted by multiplying the ACS benchmarks by 0.99. Occasional shorter-length ABC/Post polls are conducted via an omnibus survey produced by SSRS of Glen Mills, PA; see methodological details here. Each telephone exchange in the landline sample is assigned to the county where it’s most prevalent.

In terms of survey content, we examine methodological statements for misleading or false claims, questionnaires for leading or biasing wording or ordering, and analyses and news releases for inaccurate or selective conclusions. ABC News/Washington Post 2020 battleground state surveys are based on 775 to 1,100 random-sample telephone interviews with adults in selected states. On disclosure, in addition to the identities of the research sponsor and field work provider, we require a detailed statement of methodology, the full questionnaire and complete marginal data. <> We recommend against reporting others, such as pre-recorded autodialed surveys, even when a random-digit dialed telephone sample is employed. In each sample, phone numbers are released for interviewing in replicates by Census region (cell) or division (landline) to allow for sample control. We analyze subgroups only as small as 100 cases (or very near it). As of April 2013, Spanish-language interviewing was added to full-length ABC/Post polls for respondents who indicate a preference to be interviewed in Spanish.

ABC News polls therefore are not weighted to the number of household phone lines. Junk in, Junk out! Our sample excludes adults who don’t have a cell or landline phone (3.2 percent, per the NHIS); who don’t speak English or Spanish (1.5 percent, per the American Community Survey conducted by the U.S. Census Bureau); and who live in institutional group facilities where individual telephone access is disallowed (chiefly, adult correctional facilities), about 0.9 percent. In November 2014 we posted online available sample dispositions for all ABC News and ABC News/Washington Post polls since 1999, and have updated them regularly since. Spanish-language interviewing in SSRS omnibus surveys began in October 2009. In sampling, phone numbers are drawn randomly from cell phone area codes and exchanges assigned to cell service provider billing centers in the state, a database of out-of-state cell phone numbers whose users are billed within the state and landlines with in-state area codes and exchanges. What the writer does not disclose is that the Washington Post / ABC poll is highly skewed to the left, so its conclusions are totally unreliable. Methodologically, in all or nearly all cases we require a probability-based sample, with high levels of coverage of a credible sampling frame. From a random start within the first sampling interval, a systematic nth selection of 100-blocks is performed and a 2-digit random number between 00 and 99 is appended to each selected 100-block stem. Interviews were conducted in English in all states, with additional Spanish interviews in Arizona and Florida. The cell phone-only proportion, based on data from the National Health Interview Survey, grew from 100 out of 1,000 interviews to 335 per 1,000 during this period. Before October 2008, full-length ABC/Post polls were conducted by calling samples of landline telephone numbers only.

A sampling interval is determined by dividing the universe of eligible 100-blocks by the desired sample size. But as with a lot of recent political polls, the president and his team can note that the survey methodology was skewed against him, like the latest ABC/Washington Post poll… Washington Post-ABC poll is an absurdity. Fact Check: Rasmussen polls the American public on Trump’s approval rating nearly every day. From October 2008 through June 2015 we added cell phone interviews via a non-overlapping dual-frame sample design, with separate sampling frames for landline and cell phone-only respondents, as detailed in this paper. in Survey Practice (2019). Given the absence of any cell phone directory, all 100-blocks in dedicated wireless exchanges and 1,000-blocks used for sampling purposes are considered active. The proportion of cell phone interviews again is driven by the NHIS estimate of cell phone-only respondents; to achieve our target, from July 2015 through February 2020 65 percent of all interviews were conducted by cell phone, with the remaining 35 percent interviewed via landline. The non-overlapping design served well, especially through a time in which cell phone interviews were much costlier than landline interviews. In the first stage of selection, the database is sorted by state and county, and the number of telephone numbers to be sampled within each county is determined using systematic sampling procedures from a random start, such that each county is assigned a sample size proportional to its share of possible numbers. It cannot be assumed that a higher response rate in and of itself ensures greater data integrity. A new ABC News/Washington Post poll.
