(redirected from R-test)

sta·tis·tics  (st-tstks)
n.
1. (used with a sing. verb) The mathematics of the collection, organization, and interpretation of numerical data, especially the analysis of population characteristics by inference from sampling.
2. (used with a pl. verb) Numerical data.

[From German Statistik, political science, from New Latin statisticus, of state affairs, from Italian statista, person skilled in statecraft, from stato, state, from Old Italian, from Latin status, position, form of government; see st- in Indo-European roots.]

statistics [stəˈtɪstɪks]
n
1. (Mathematics & Measurements / Statistics) (functioning as plural) quantitative data on any subject, esp data comparing the distribution of some quantity for different subclasses of the population statistics for earnings by different age groups
2. (Mathematics & Measurements / Statistics) (functioning as singular)
a.  the classification and interpretation of such data in accordance with probability theory and the application of methods such as hypothesis testing to them
b.  the mathematical study of the theoretical nature of such distributions and tests See also descriptive statistics, statistical inference
[C18 (originally ``science dealing with facts of a state''): via German Statistik, from New Latin statisticus concerning state affairs, from Latin status state]

sta•tis•tics (stəˈtɪs tɪks)

n.
1. (used with a sing. v.) the science that deals with the collection, analysis, and interpretation of numerical data, often using probability theory.
2. (used with a pl. v.) the data themselves.
[1780–90; orig., a branch of political science dealing with the collection of data relevant to a state < German Statistik]

statistics  (st-tstks)
1. (Used with a singular verb) The branch of mathematics that deals with the collection, organization, analysis, and interpretation of numerical data. Statistics is especially useful in drawing general conclusions about a set of data from a sample of the data.
2. (Used with a plural verb) Numerical data.

decile - (statistics) any of nine points that divided a distribution of ranked scores into equal intervals where each interval contains one-tenth of the scores

deviation - the difference between an observed value and the expected value of a variable or function
moment - the n-th moment of a distribution is the expected value of the n-th power of the deviations from a fixed value
distribution free statistic, nonparametric statistic - a statistic computed without knowledge of the form or the parameters of the distribution from which observations are drawn
