Description
Polls and surveys have been used for better forecasting voter preferences and understanding consumer behavior. Academically we employ the strength of these smaller but representative data to confirm theory, including identifying associations between theoretically identified variables. However, researchers who like to explore new patterns for better understanding voters' behavior and attitudes are hardly satisfied by the current practice of survey data analysis. While we turn to bigger data, little attention has been preserved to the value of such smaller data for their potential to achieve the same goal. This talk will demonstrate how the use of "FactorMineR" package of R assists exploration of associated concepts and attitudes and patterns that could not be identified by theories in the first place. Implications for the practice of survey data collection and MCA's connection to association rules mining will be discussed.
