The majority of past literature employed conventional market segmentation variables such as geographic variables and benefit variables. However, since Sproles and Kendall developed the concept of decision making styles in 1986 to segment markets, there has been changes in consumer segmentation variables. In this study, instead of covering only university students in the sampling pool and conducting exploratory factor analysis or confirmatory factor analysis for statistical analysis, consumer decision making styles in Taiwan are investigated through empirical analysis. Research results found that there are eight different types of decision making styles within Taiwanese consumers and that these styles are consistent with the consumer market in the U.S.
