    • In statistics, the term analysis may refer to any method used for data analysis. Among the many such methods, some are:
      • Analysis of variance (ANOVA) – a collection of statistical models and their associated procedures which compare means by splitting the overall observed variance into different parts
      • Boolean analysis – a method to find deterministic dependencies between variables in a sample, mostly used in exploratory data analysis
      • Cluster analysis – techniques for grouping objects into a collection of groups (called clusters), based on some measure of proximity or similarity
      • Factor analysis – a method to construct models describing a data set of observed variables in terms of a smaller set of unobserved variables (called factors)
      • Meta-analysis – combines the results of several studies that address a set of related research hypotheses
      • Multivariate analysis – analysis of data involving several variables, such as by factor analysis, regression analysis, or principal component analysis
      • Principal component analysis – transformation of a sample of correlated variables into uncorrelated variables (called principal components), mostly used in exploratory data analysis
      • Regression analysis – techniques for analyzing the relationships between several variables in the data
      • Scale analysis (statistics) – methods to analyze survey data by scoring responses on a numeric scale
      • Sensitivity analysis – the study of how the variation in the output of a model depends on variations in the inputs
      • Sequential analysis – evaluation of sampled data as it is collected, until the criterion of a stopping rule is met
      • Spatial analysis – the study of entities using geometric or geographic properties
      • Time-series analysis – methods that attempt to understand a sequence of data points spaced apart at uniform time intervals

    • QUOTE: early 14c., "a quantity of labor imposed as a duty," from Old North French tasque (12c., Old French tasche, Modern French tâche) "duty, tax," from Vulgar Latin *tasca "a duty, assessment," metathesis of Medieval Latin taxa, a back-formation of Latin taxare "to evaluate, estimate, assess" (see tax (v.)). General sense of "any piece of work that has to be done" is first recorded 1590s. Phrase take one to task (1680s) preserves the sense that is closer to tax.

      German tasche "pocket" is from the same Vulgar Latin source (via Old High German tasca), with presumable sense evolution from "amount of work imposed by some authority," to "payment for that work," to "wages," to "pocket into which money is put," to "any pocket."

    • QUOTE: Analysis is the process of breaking a complex topic or substance into smaller parts to gain a better understanding of it. The technique has been applied in the study of mathematics and logic since before Aristotle (384–322 B.C.), though analysis as a formal concept is a relatively recent development.[1]

      The word is a transcription of the ancient Greek ἀνάλυσις (analusis, "a breaking up", from ana- "up, throughout" and lysis "a loosening").
