In statistics, scale analysis is a set of methods to analyze survey data, in which responses to questions are combined to measure a latent variable. These items can ...
The Affective Slider is an empirically validated digital scale for the self-assessment of affect composed of two slider controls that measure basic emotions in terms of pleasure and arousal, [6] which constitute a bidimensional emotional space called core affect, that can be used to map more complex conscious emotional states.

A rating scale is a set of categories designed to obtain information about a quantitative or a qualitative attribute. In the social sciences , particularly psychology , common examples are the Likert response scale and 0-10 rating scales, where a person selects the number that reflecting the perceived quality of a product .
In probability theory, an empirical measure is a random measure arising from a particular realization of a (usually finite) sequence of random variables.The precise definition is found below.
Robust measures of scale can be used as estimators of properties of the population, either for parameter estimation or as estimators of their own expected value.. For example, robust estimators of scale are used to estimate the population standard deviation, generally by multiplying by a scale factor to make it an unbiased consistent estimator; see scale parameter: estimation.

Run the Alpha in the statistical program (asking for the Alpha's if each item is dropped). Any scales with insufficient Alphas should be dropped and the process repeated from Step 3. [Coefficient alpha=number of items 2 x average correlation between different items/sum of all correlations in the correlation matrix (including the diagonal values)]
Level of measurement or scale of measure is a classification that describes the nature of information within the values assigned to variables. [1] Psychologist Stanley Smith Stevens developed the best-known classification with four levels, or scales, of measurement: nominal, ordinal, interval, and ratio.
