It will be discussed if the confidence in the results of the production of economic and social data will be justified. Probability based conclusions are possible concerning the sampling error. In order to quantify the non-sampling error an accuracy check is necessary which causes practical...

In this article results of the two experiments, aimed at the development of the instrument (test) that would enable construction of the comprehensive measure of individual overconfidence for the use in economic overconfidence experiments, are presented. Instrument was obtained in a two-stage...

Systematic investigations of the cognitive challenges in completing time diaries and measures of quality for such interviews have been lacking. To fill this gap, we analyze respondent and interviewer behaviors and interviewer-provided observations about diary quality for a computer-assisted...

This research paper investigates the level of product quality based on the dimensions of quality. Customers' priorities when purchasing a two wheeler have been analyzed for different manufacturers using a structured questionnaire. This study uses both an empirical and a fuzzy logic approach to...

The study investigated sustainable supply chain management (SSCM) practices pertaining to environmental perspective of manufacturing companies in India. Using factor analysis, the study identified three dimensions under environmental. It included companies from distinct sectors. Sample was...

Atheoretical measure purification may lead to construct deficient measures. The purpose of this paper is to provide a theoretically driven procedure for the development and empirical validation of symmetric component measures of multi-dimensional constructs. We place particular emphasis on...

The timing of sexual partnerships constrains the potential flow of sexually transmitted infections (STIs). It is crucial to determine the quality of reported data on sexual partnership timing for both scientific and practical purposes. Temporal data on partnerships are used in contact tracing...

Inference from Web surveys may be affected by non-random selection of Web survey participants. One approach to reduce selection bias is to use propensity scores and a parallel phone survey. This approach uses demographic and additional so-called Webographic or lifestyle variables to balance...

We study the effect of attrition and other forms of non-response on the representativity over time of the Health and Retirement Study (HRS) sample born 1931-1941; the sample was initially drawn in 1992. Although some baseline characteristics of respondents do appear correlated with non-response over...

Web surveys have several advantages compared to more traditional surveys with in-person interviews, telephone interviews, or mail surveys. Their most obvious potential drawback is that they may not be representative of the population of interest because the sub-population with access to Internet...
