Method for selecting respondents for query in a respondent query system

摘要

A method of interrogating respondents from one or more populations of potential respondents with an interrogator (200) configured to send question signals (210) to any respondent and response signals (220) from the respondents in response to the questions receives, the method comprising one or more surveys. Each survey comprises at least two twisits of a query cycle, comprising: (a) a selection step for respondents, in which the interrogator (200) selects a subset from one or more respondents, (b) a query step in which the interrogator (200) selects one or more respondents sends several question signals (210) to one or more respondents of the subset and (c) a response step in which the interrogator (200) receives response signals (220) from these respondents that respond to the question signal (s) (210) of the Interrogators (200) respond. In at least one of the surveys in the selection step of at least one twisit other than the first twisit of the survey, the interrogator (200) uses information about at least some of the respondents from whom the interrogator (200) received an answer in an earlier twisit of the same survey . In at least one of the surveys in the selection step of at least one twisit, the interrogator (200) uses information to load queries about at least some of the potential respondents. In at least one of the surveys in the first phase of the query cycle in the selection step, the interrogator assigns at least some of the respondents to the subset in an order in which the contribution they make to the representativeness and / or diversity of the subset in relation to one or more is taken into account of the population (s).
