The author introduce how the range and the number of attribute levels affect measures of attribute importance implemented by traditional conjoint analysis. We find that the relative importance of attribute are affected by the range manipulation and the number of attribute levels. The results show that the extension of both end-point attribute levels increases the importance of attribute. Also conjoint importance estimates increases by the insertion of intermediate attribute levels. However, the attribute importance estimated by self-explicated method does not vary with the variation of attribute level range and number of attribute levels. Therefore, these results imply that we need to select carefully the attribute levels of stimuli which the respondents are exposed to in purchasing situation.
