ATTRACTIVE OR NOT – WHAT'S THE DIFFERENCE? INTER- AND INTRA-GROUP COMPARISONS IN THE KANO MODEL
52 younger and 52 older adults expressed their responses to fulfillment and absence of product attributes, which have been previously identified as crucial aspects of technology adoption. The aim of the study was to investigate whether older and younger adults differ with respect to their priorities concerning product appraisal. Additionally, statistical intra-group comparisons were introduced to allow the consideration of tied ranks. These equate to market segments of groups that are represented similarly often, but with different expectations. Significant age differences were found.
