Analysis Plan TitleExamining the Comparability Between the iCARE Canadian Representative and Convenience Samples
Analysis Plan DescriptionOVERVIEW: The iCARE project involves a number of datasets collected through convenience-based sampling, along with data collected to be representative of certain countries. Although the potential of convenience sampling to introduce bias has been discussed at length, there have been fewer empirical examinations with large convenience and large representative samples to see how these biases play out when using the same survey instrument. The current project aims to examine: (1) the degree to which the iCARE convenience and Leger samples differ from census-based data, and (2) examine how findings differ between the two types of samples by examining associations to variables such as concerns and behaviours. METHODS: The data used for this study involve the current available waves of convenience and representative sampling for Canada within the iCARE project. We will examine the degree to which means/proportion across variables are similar across the two types of sampling. Analyses will be conducted across a larger set of variables to increase the generalizability of findings.
