Sampling is not as easy as it used to be. That's why we offer Advanced Sampling Solutions.
Changing social norms and new technology give people more ways to be reached – or stay out of reach. How do you develop a sampling plan that results in statistically sound data? Especially when you're working on a tracking project that has been running since the days of mail surveys?
MSG's team of statistical sampling experts will help you design a sample that meets the strictest requirements to ensure your data is accurate, defensible, and appropriate for your project, including imputation to adjust for missing data.
Split Frame Samples are disproportionate stratified samples (DSS) where the target segment of the sample frame is sampled at a higher rate relative to the frame in total. This design is typically used to adequately sample hard-to-reach targets such as minorities within a larger sample frame. Split frame samples contain all of the information necessary to calculate universe estimates for weighting.
Dual Frame Samples use two separate sample frames to interview a population of interest. The most common dual frame sampling design in use today utilizes both landline and cellular RDD telephone sample frames. Dual frame samples contain all of the information necessary to calculate universe estimates for weighting.
Multi Mode Samples can maximize your survey response rate by employing a mixture of different contact methods. Using multiple methods to contact respondents, such as by phone, mail, and online, results in a more representative sample of the target population. Overall response rates can be improved because different methods meet different respondent preferences. MSG's multi frame samples use properly integrated sampling frames without introducing duplication of individual respondents.
