Testing different rank order question layouts for PC and smartphone respondents

We studied the impact of different layouts for rank order questions on respondent effort, data quality, and substantive results among PC and smartphone respondents, in an experiment in an opt-in online panel in Spain, using an order-by-click design. We experimentally varied the device, the number of columns, and, for smartphone respondents, the position of the ‘next’ button in questions on trust in institutions.

We found some evidence of lower data quality for smartphone users but no evidence that presenting ranking items in one column performs differently than two columns. We also find little evidence that these effects differ by the number of response options presented or the number to be ranked. The placement of the ‘next’ button had little effect on performance on ranking items. Overall, our findings suggest that the format and layout of order-by-click questions has little effect on data quality, regardless of device used.     

When near means related: evidence from three web survey experiments on inter-item correlations in grid questions

In this article, we present the results of three question design experiments on inter-item correlations, which tested a grid design against a single-item design. The first and second experiments examined the inter-item correlations of a set with five and seven items, respectively, and the third experiment examined the impact of the question design on inter-item correlations of follow-up questions. We found that the inter-item correlations in grid designs were higher for both the set of five and seven items than for questions in a single-item design. Additionally, the inter-item correlations of the set of follow-up questions were higher if the preceding set of questions was presented in a grid. According to the findings of the present research, respondents seem to apply the interpretative near means related heuristic when answering grid questions, and also when answering follow-up questions preceeded by grid questions.

基本养老保险收支测算中职工人数模型的探讨

职工人数测算在养老保险收支测算中居重要地位,通常使用的时间序列法,受波动性因素影响测算结果误差较大,在保障水平固定时误差直接表现为基期收支与实际不符。为了更准确地模拟职工年龄结构的变化,本文采用OLG方法,建立年龄变化相对稳定的职工人数递推模型。通过基期数据的对比检验,我们发现退休职工增速远大于正常的企业职工退休速度,参保职工人数测算口径偏小是造成这一现象的主要原因。
