Typically, data collection with these panels is done online. However, the chance that each selected person will join the panel or take surveys after joining is not known. Some opt-in samples are sourced from a panel or multiple panels , while others rely on intercept techniques where respondents are invited to take a one-off survey.

For example, survey-based estimates for the share of voters who voted for each candidate in the presidential election are compared to a benchmark based on an official tally by the Federal Election Commission FEC.

Survey estimates are deemed more accurate the closer they are to the benchmark value. In this study, the benchmarks come from high-quality federal surveys such as the American Community Survey or administrative records like the FEC vote tally. Error: This is the difference between an individual survey estimate and its corresponding benchmark value.

Error can be either positive or negative depending on whether the survey estimate is higher or lower than the benchmark. Absolute error: This is the absolute value of the error for a survey estimate. It describes the size of the error irrespective of its direction positive or negative.

Average absolute error for a benchmark variable : This is a measure that summarizes the average size of errors across all the categories within a single benchmark variable. For example, the smoking status variable has four categories: 1 Smoke every day, 2 Smoke some days, 3 Do not now smoke and 4 Never smoked cigarettes.

For a given survey, the absolute error for the smoking status variable is equal to the sum of the absolute errors for each category divided by the number of categories.

Average absolute error for a sample : Average absolute error can also be used to summarize the overall level of error across many different benchmarks within a single sample. When used in this context, the average absolute error for a sample is equal to the sum of the average absolute errors for each benchmark variable divided by the total number of benchmark variables.

As the field of public opinion research continues its steady movement toward online data collection, probability-based panels and opt-in samples have emerged as the two most common approaches to surveying individuals online. At the same time, the methodologies and industry practices for both kinds of samples are evolving.

To shed light on the current state of online probability-based and opt-in samples, Pew Research Center conducted a study to compare the accuracy of six online surveys of U. adults — three from probability-based panels and three from opt-in sources.

This is the first such study to include samples from multiple probability-based panels, allowing for their side-by-side comparison. The surveys in this study were administered between June 14 and July 21, , and included interviews with a total of 29, U.

adults, approximately 5, in each sample. Because this is a methodological study, the names of the sample providers are masked. Refer to the appendix for the full list of benchmarks and their sources. For estimates among U.

adults on 28 benchmark variables, opt-in samples 1, 2 and 3 had average absolute errors of 6. This was about twice that of the probability-based online panels, for which average absolute error was 2.

On 25 variables for which subgroup-level benchmarks were available, the online opt-in samples averaged adults overall 6. By comparison, the average absolute error on the probability-based panels was 3.

We have been regularly tracking variants of the virus throughout the pandemic to provide information to the CDC. The sensitivity of our PCR test is not impacted by the following known variants. For a full list of variants detected by the Labcorp PCR test, visit Labcorp.

The Pixel by Labcorp COVID at-home kit is a molecular test, also known as a reverse polymerase chain reaction RT-PCR test or a nucleic acid amplification test NAAT. This test detects the presence or absence of SARS-CoV-2, the virus that causes COVID Your test results will confirm whether or not you are infected with SARS-CoV If your results are positive, it is important to limit your exposure to other people and continue to monitor your symptoms.

If your results are negative, the virus was not present in the sample you provided. However, it is important to note that the virus may not be detected by the test in early stages of infection. Furthermore, the virus may not be detected if the sample is not collected as directed.

If you have reason to believe you have been exposed, it is important to follow up with a healthcare provider for further evaluation, get re-tested, and follow isolation or quarantine precautions as recommended. After receiving your results, you will have the opportunity to speak with a licensed physician who can answer any questions you may have about your test results and help determine next steps in care.

Though patients can recover from COVID on their own, some patients are at risk for becoming seriously ill. There are now treatments available to assist with COVID recovery, such as monoclonal antibodies, oral antivirals, or hospital treatments like antiviral drugs or convalescent plasma.

On 25 variables for which subgroup-level benchmarks were available, the online opt-in samples averaged adults overall 6. By comparison, the average absolute error on the probability-based panels was 3. A similar level of error was seen on the probability-based panels for other traditionally hard-to-survey subgroups such as those with no more than a high school education 3.

On each of the probability-based panels, the number of benchmarks for which average absolute error was greater than 5 percentage points ranged from two to five out of About half between 14 and 15 benchmarks had under 2 points of average absolute error.

Large errors were more widespread on the opt-in samples, which had between 11 and 17 benchmarks with error greater than 5 points. Fewer benchmarks between three and seven on the opt-in samples had average absolute error below 2 points. This suggests that despite the inclusion of volunteerism and voter registration in weighting adjustments, the overrepresentation of politically and civically engaged individuals remains an important challenge for probability-based panels.

It is highly unlikely that the few individuals who do fit that description are massively overrepresented in online opt-in samples.

Polling insiders may wonder why we conducted this study. Other research teams including our own several years ago have done similar comparisons and arrived at the same result : Probability-based samples tend to be more accurate, even if recent election polls are an exception.

One major reason we conducted this study is because it offers something new. This benchmarking study is the first to estimate the accuracy of multiple online probability-based panels in the United States.

This allows us to answer a previously unaddressed question: Do different probability-based panels tend to offer similar data quality or not? The three probability-based panels tested in this study performed about the same. The average absolute error ranged from just 2.

The study reported here is, in part, our effort to measure whether those improvements made a difference, allowing us to determine how the new, improved ATP stacks up against opt-in samples and against other probability-based panels.
