Practical Guide for Surveys Based on Nonprobability Samples Mansour Fahimi,Frances Barlas, and Randall Thomas, will be recorded in February 2018. This webinar will will begin with an overview of different types of nonprobability samples and discuss their pros and cons from a fitness for use perspective. Focusing on online surveys, we will cover best practices for sourcing and selection of such samples, including effective options for sample balancing, incentive options, and considerations for data quality given the vast and varied landscape of sample providers. Lastly, we will lay the foundation for our next webinar on robust weighting and calibration methodologies that can reduce some of the inherent biases of such samples, as well as optimal methods for blending probability and nonprobability samples. We will end this webinar with some contemplations about the new directions in survey sampling in the digital age.
