9-point category scale

White American military personnel for selected desserts and beverages. Modified from Meiselman (1977). Hedonic ratings based upon 9-point category scale developed by Peryam and Pilgrim (1957). 

In this example, the consumers are asked to rate both their perceived and ideal intensities on a 100 mm line scale, with anchor points at 10 and 90. No restrictions concerning the scale used are given, except that it should be identical for both the perceived and ideal intensities. Additionally, the consumers are asked to rate the products on liking. Specific liking questions can also be asked. For hedonic questions, a 9-point category scale is used. 

Different types of category scales have been used to evaluate wound odor in clinical settings by either health practitioners or patients. For example, many clinical trials have used a four-point category scale comprising no odor, little, moderate, and severe... 

Ordinal scale Samples are ranked for a single specific characteristic. Ordinal data are used for category scaling . The tasters are asked to rate the intensity of a sensorial stimulus by assigning a score on a limited verbal or numerical scale. The number of points on the scale used for the determination of the different flavor attributes can differ by 5, 7, 9, and 10 points. Usually a description is attached to each value. In this scale the data are merely ordinal and intervals are not equidistant. The size of the difference between two values cannot be assumed to reflect the difference between the perceived intensities. 

Hedonic scaling can be achieved using a five-, seven-, or nine-point scale. Such category scales are based on nonequal interval spacing, and for this are treated as ordinal scales. An alternative approach is to ask respondents to indicate their hedonic response... 

Children aged 8-9 were shown to be able to estimate the intensity of sweetness in a suitable way compared to adults, by comparing category scale, magnitude estimation and hand separation (James et al, 2003). A nine-point scale was successfully applied to the evaluation of the intensity of sweetness and creaminess in children aged 8-10 and 11-14 years, but the researchers used pair comparisons to evaluate perceptions in children aged 5-7 years (Lavin and Lawless, 1998). A five-point scale was used to describe perception of sweetness intensity throughout the age span from 6 years ... 

Finally, as regards the choice of scale, Doty (1991) argued that the simplicity and robustness of category scales make them very appropriate to elderly studies. In fact, in the study described in Section 23.4, it was observed that older subjects were using a seven-point hedonic scale in a repeatable and discriminative way. In Kremer et al. s study (2007), evaluations were made from visual analogic scales. All the previous...
