Exemplary embodiments are directed to respondent selection approaches for surveys, such as online surveys. The respondent selection approaches can be provide a selection process that is source independent to select individual respondents based on characteristics of the individual respondents, rather than based on characteristics of the source (e.g., group) with which the respondent is associated. Exemplary embodiments can advantageously use an estimate of a propensity score to select respondents for a survey before the survey is conducted. |
