Document Summary
Process of measuring or ordering entities in respect to quantitative attributes. Give those attributes a list, and group them to stronger or weaker variables. Cluster of questions, which tap into a unitary dimension of behaviour, attitude or feeling. Measuring one concept in a scale, everything is related. Constructed by accumulating scores assign to individual attributes. Index contribute to scores in a dimension, not as specific as a scale. Combination of several empirical indicators into a single measure. Inadequacy of a single indicator when we have multiple indicators each indicator reflects a distinct aspect of the dimensions. Compensate measurement has a better range of variation. Index: accumulate scores assigned to individual attributes. Scale: assign scores to patterns of responses. Has an intensity structure among the attributes. Indexes are easier to create, scale is better. Scales are predictive of outcomes, an ordinal list.
