Abstract: | In this research the impact of two types of end anchors on the linearity of the category rating scale is studied. Two functional
measurement experiments were carried out, each requiring a different kind of judgement, i.e., job satisfaction ratings and
attractiveness ratings. One group of participants rated the stimuli using a category rating scale with fixed anchors, while
another group was presented with a self-anchoring category rating scale. The results indicate that researchers can be confident
in the ability of both category rating scales to provide linear data. This implies that the different end anchors do not impact
on the linearity of the category rating scale. |
