(1). Apparatus for measuring the weight of an object. (2). In sensory evaluation, a mathematical representation of the perceived intensity of an attribute, or response to a food, using a continuum divided into successive values. Typically, the intervals on the scale are allocated sequential numbers, but they can be identified by symbols or be identified only at the ends of the continuum, and the assessor must interpolate between them. An example is a numeric scale for intensity of a stimulus, in which 0=absent, 1=very weak, 2=weak, 3=moderately strong, 4=strong, and 5=very strong. In this case, the scale is fully structured, i.e. Each interval is labelled. A line scale consists of a line, say 10 cm long, drawn on the score sheet and labelled at the ends with the extremes of the scale, for example, absent and very strong, and perhaps also labelled in the middle.
