Statistical analysis of a data set may reveal that two variables (that is, two properties of the population under consideration) tend to vary together, as if they are connected.
For example, the statistical significance of a trend in the data — which measures the extent to which the trend could be caused by random variation in the sample — may not agree with one's intuitive sense of its significance.
A common goal for a statistical research project is to investigate causality, and in particular to draw a conclusion on the effect of changes in the values of predictors or independent variables on response or dependent variables.

In contrast, mathematical statistics (or simply statistical theory) is the subdiscipline of applied mathematics which uses probability theory and analysis to place statistical practice on a firm theoretical basis.
The word statistics is also the plural of statistic (singular), which refers to the result of applying a statistical algorithm to a set of data.

Statistics is the science and practice of developing human knowledge through the use of empirical data.
Because the aim of statistics is to produce the "best" information from available data, some authors make statistics a branch of decision theory.
The word statistics comes from the modern Latin phrase statisticum collegium (lecture about state affairs), from which came the Italian word statista, which means "statesman" or "politician" (compare to status) and the German Statistik, originally designating the analysis of data about the state.

Statistics in the broader sense covers the whole spectrum of techniques used to study random phenomena.
Statistics makes it possible not only to take into account the noise present in the data, but also the heterogeneity of the models studied and the atypical values that may occur.
Statistical tests, resampling techniques such as cross-validation or bootstrap-that are very much used in statistical learning-the Bayesian approach that leads to the construction of model selection criteria that compensate a model adjustment quality with a measure of its complexity, these are powerful statistical inference tools to accomplish such a difficult task.

Among other problems, he considered statistics of specular points (the points at which the gradient of the field is either zero or is specified depending on a viewing angle) and of the wave envelope, which play an important role in wave dynamics and analysis of sun glitter and radar backscatter from a wind-disturbed sea surface.

 Statistical Mechanics of Cellular Automata (1983)
Cellular automata are used as simple mathematical models to investigate self-organization in statistical mechanics.
A detailed analysis is given of ``elementary'' cellular automata consisting of a sequence of sites with values 0 or 1 on a line, with each site evolving deterministically in discrete time steps according to definite rules involving the values of its nearest neighbors.
Statistical properties of the structures generated are found to lie in two universality classes, independent of the details of the initial state or the cellular automaton rules.

Quantitative analysis thus enables one to separate the wheat from the chaff: it enables one to discover which phenomena are likely to be genuine reflections of the behaviour of a language or its variety and which are merely chance occurrences.
For statistical purposes it is necessary to decide strictly either an item belongs to class A or it does not.
Consequently, linguistic phenomena can be assigned relative probabilities and thus we may evaluate with some degree of certainty the occurrence of the phenomena.

However, when statistical tests are used in situations beyond their ordinary application, they can result in rejections of the null hypothesis for reasons other than a presumed departure from the expected chance value.
Although it is consistent with scientific practice to use statistical inference to reject the null hypothesis, it is not consistent with such practice to postulate the existence of phenomena on this basis alone.
The phenomena that can be observed with the standard exemplars do not require sensitive statistical rejections of the null hypothesis based on many trials to announce their presence.

This is not to deny the empirical occurrence of phenomena that lend weight to the mathematical models used by statisticians, but rather to suggest that their relative prominence in our collective imagination reflects the way we experience society at different times.
In the 20th century this model was the basis for the development of "parametric" statistics, the mainstream approach to statistical inference.
This whole paradigm shift in scientific and statistical models seems to coincide with the breakdown of the nation-state as the monopolistic framework of society and with it of the corporate premises of 20th century economy, jobs for life and all that.

The point is to arrive at an understanding of phenomena -- whether that phenomena is statistical in nature or whether it is non-statistical in nature.
Regardless of who finds out phenomena, whether it is qualitative or quantitative, probable or exact, a theory meant to explain a subject must explain or give a logical account of relevant known phenomena, and predict phenomena not known at the time.
Statistical studies can be a help in finding out what factors to try to study in isolated ways, or what factors to try to think about logically as to how they might contribute to understanding the problem.

Responding to these remarks, Broca acknowledged the limits of population statistics to treat a case of pneumonia, but insisted on their relevance for the analysis of a statistical phenomena such as depopulation (Bulletin, 1866-67: 854).
Viewed from this perspective, Guerin's proclamations concerning the "arbitrariness of statistical calculations" (versus etiologic causality) can be read either as an affirmation of the descriptive form of statistical reasoning--which excluded the use of statistics to identify causes--or as an expression of his inability to fully comprehend, and thus match, Broca's statistical reasoning.
One of the striking features of both these controversies concerns the contribution of this particular mode of articulation to the advancement of statistical savoir faire and to the introduction of new forms of statistical reasoning, be it inferential reasoning in the 1840s or mathematical modeling in the 1900s.
