J.G. Bethlehem Reducing the bias of web survey based estimates
At first sight, web surveys seem to be an interesting and attractive means of data collection. They provide simple, cheap and fast access to a large group of people, and they offer all kinds of new possibilities such as use of sound, video and animation. However, there is another side to this coin. Due to methodological problems, outcomes of web surveys may be severally biased. Specific groups in the populations are under-represented among Internet users. Moreover, many web surveys apply self-selection...

Fannie Cobben Mode effects in a basic question approach for the Dutch LFS
From July to October 2005, a sample of non-respondents to the Dutch Labour Force Survey (LFS) was once more approached with strongly condensed questionnaires containing only a small number of emphbasic question. The main goal of this so-called Basic Question Approach (BQA) is to gain insight in possible differences between respondents and non-respondents with respect to the most important variables of the survey

Jan A. van den Brakel | Paul Smith | Simon Compton Quality procedures for survey transitions experiments and discontinuities
To maintain uninterrupted time series, surveys conducted by national statistical institutes are often kept unchanged as long as possible. When a change is proposed to improve the methods, it may affect the continuity of these series. It is important to minimise the impact so as to minimise the inconvenience for users. In this paper we set out the steps in an orderly transition, provide practical guidance on how to minimise discontinuities, and review methods for dealing with discontinuities if they...

B. Schouten A follow-up of nonresponse in the Dutch Labour Force survey
From July to December 2005 a large scale follow up of nonrespondents in the Dutch Labour Force Survey (LFS) was conducted at Statistics Netherlands. In the study a sample of non-respondents in the LFS was approached once more by a small number of selected interviewers. The sample consisted of LFS households that refused, were not processed or were not contacted in the LFS of the months July - October. Approximately 43% of the initial non-respondents participated in the followup study, leading to...

Fannie Cobben | B. Schouten A follow-up with basic questions of nonrespondents to the Dutch labour force survey
From July to December 2005 a large scale follow up of nonrespondents in the Dutch Labour Force Survey (LFS) was conducted at Statistics Netherlands. In the study a sample of nonrespondents in the LFS was approached once more with strongly condensed CATI, web and paper questionnaires containing only the key questions of the LFS; the basic-question approach. We analysed the additional response obtained in the basic-question approach and compared the composition of this group to the LFS response. There...

B. Schouten | Fannie Cobben R-indexes for the comparison of different fieldwork strategies and data collection modes
Many survey organisations focus on the response rate as being the quality indicator for the impact of non-response bias. As a consequence they implement a variety of measures to reduce non-response or to maintain response at some acceptable level. However, in general response rates are not good indicators of non-response bias. Response rates only relate to the accuracy of estimators and also limits the maximal impact of non-response under the worst case scenario. In that respect it is worthwhile...

Deirdre Giesen | Tony Hak Revising the structural business survey
from a multi-method evaluation to design
This paper describes the evaluation and redesign of the Structural Business Survey questionnaire. We describe how and to what extent various evaluation methods contributed to our understanding of the main problems of the SBS questionnaires and how some of the evaluation results could be translated straightforwardly into solutions. We discuss in some detail why our evaluation findings were not decisive on the issue of the desirable approach to the overall structure of the questionnaires and how we...

Wieger Coutinho | A.G. de Waal | Marco Remmerswaal Imputation of numerical data under linear edit restrictions
A common problem faced by statistical offices is that data may be missing from collected data sets. The typical way to overcome this problem is to impute the missing data. The problem of imputing missing data is complicated by the fact that statistical data often have to satisfy certain edit rules, which for numerical data usually take the form of linear restrictions. Standard imputation methods for numerical data as described in the literature generally do not take such linear edit restrictions...

Jan A. van den Brakel Design-based analysis of embedded experiments with applications in the Dutch labour force survey
In a series of papers a design-based analysis procedure is proposed for experiments embedded in complex sampling designs in which the ultimate sampling units of an ongoing sample survey are randomized over different treatments according to completely randomized designs or randomized block designs. Design-based Wald and t-statistics are applied to test hypotheses about differences between sample means observed under different survey implementations, Van den Brakel and Renssen (1998, 2005) and Van...
