Comparing the Accuracy of Univariate, Bivariate, and Multivariate Estimates across Probability and Nonprobability Surveys with Population Benchmarks [PDF]

Sociological Methodology
Previous studies have shown many instances where nonprobability surveys were not as accurate as probability surveys. However, because of their cost advantages, nonprobability surveys are widely used, and there is much debate over the appropriate settings

Selection Bias in Nonprobability Surveys: A Causal Inference Approach [PDF]

, 2018
Many in the survey research community have expressed concern at the growing popularity of nonprobability surveys. The absence of random selection prompts justified concerns about self-selection producing biased results and means that traditional, design ...

Correction for Participation Bias in Nonprobability Samples Using Multiple Reference Surveys. [PDF]

Stat Med
ABSTRACT Health researchers are increasingly adopting nonprobability sampling strategies in survey studies. However, the participation mechanism in such samples is unknown and estimated target parameters and exposure‐outcome associations obtained from nonprobability samples can be biased.

Probability vs. Nonprobability Sampling: From the Birth of Survey Sampling to the Present Day

Statistics in Transition new series, 2023
At the beginning of the 20th century, there was an active debate about random selection of units versus purposive selection of groups of units for survey samples. Neyman's (1934) paper tilted the balance strongly towards varieties of probability sampling

Evaluation of available techniques and their combinations to address selection bias in nonprobability surveys

AStA Advances in Statistical Analysis
Abstract New survey methodologies that often produce nonprobability samples have recently become very important. However, estimates from nonprobability samples can be subject to selection bias, which is primarily caused by the lack of coverage and the respondent’s ability to decide whether or not to participate in the survey.

A Demonstration of Propensity-Score Weighting to Adjust a Social Media Nonprobability Sample Survey of Political Attitudes. [PDF]

Public Opin Q
Abstract Interest in using nonprobability online samples continues to grow despite concerns about selection bias. Many methods exist for adjusting nonprobability data so it may yield generalizable inferences. Here we investigate whether a propensity score weighting method can balance differences between a probability sample and a ...

Relations Between Variables and Trends Over Time in Rdd Telephone and Nonprobability Sample Internet Surveys

Journal of Survey Statistics and Methodology, 2020
Abstract Survey researchers today can choose between relatively higher-cost probability sample telephone surveys and lower-cost surveys of nonprobability samples of potential respondents who complete questionnaires via the internet. Previous studies generally indicated that the former yield more accurate distributions of variables, but ...

Improving the Reliability of a Nonprobability Web Survey: Application to Measuring Gender Pay Gap

International Journal of Social Research Methodology
Nonprobability web surveys suffer from selection and coverage biases and are generally not representative of the target population. To carry out statistical modelling in a nonprobability web survey, we explore different methods of statistical adjustments

New data strategies: nonprobability sampling, mobile, big data

Quality Assurance in Education, 2018
Purpose Researchers now have more ways than ever before to capture information about groups of interest. In many areas, these are augmenting traditional survey approaches – in others, new methods are potential replacements.
