Abstract:
|
This paper builds and advances a previous publication on how to compute response metrics for online panels (Callegaro & DiSogra, 2008). It starts by describing how multi-stage response rates are computed for probability-based web panels (recruitment, profile, and completion rate) and their use in a cumulative response rate calculation. We then focus on standing panels that rely on continuous recruitment from multiple independent recruitment samples and the concept of recruitment cohort. We will also present a special case for studies that use a screener and refinements that take panel attrition rates into account. Lastly it is discussed how to combine mixed mode recruitment methods in the computation of the recruitment rate.
