Understanding Survey Design Effects: Is Cluster Sampling a False Economy?
For convenience and to save on fieldwork costs, many random samples involve an
element of clustering. This session sets out to discuss how clustering of a
sample can have a detrimental effect on its statistical reliability, reducing
effective sample size, and how precision can be improved more effectively by
increasing the number of clusters, rather than increasing the number of
respondents per cluster. It will also illustrate more generally how aspects of
the design of a survey could have quite profound effects on the precision of its
results.
