One of the principal sources of error in data collected from structure
d face-to-face interviews is the interviewer. The other major componen
t of imprecision in survey estimates is sampling variance. It is rare,
however, to find studies in which the complex sampling variance and t
he complex interviewer variance are both computed. This paper compares
the relative impact of interviewer effects and sample design effects
on survey precision by making use of an interpenetrated primary sampli
ng unit-interviewer experiment which was designed by the authors for i
mplementation in the second wave of the British Household Panel Study
as part of its scientific programme. It also illustrates the use of a
multilevel (hierarchical) approach in which the interviewer and sample
design effects are estimated simultaneously while being incorporated
in a substantive model of interest.
