Limitations of Semantic Differential Scales • Respondents will misuse • Don’t read instructions and unfamiliar with SD scales • Difficult to construct • Limited to only a few words • Negation not necessarily opposite • Not black, which includes all colors, is not opposite of black • No advantage relative to Likert scales
Limitations of Profile Analysis • Few brands can be depicted • Attributes are non-independent • Profiles not weighted by attribute importance
