Statistics is the science of obtaining, synthesizing, predicting, and drawing inferences from data. Elementary calculations of mean and standard variation suffice to summarize a large, finite, normally-distributed dataset; the field of Statistics exists since data are not usually so nicely given. If we do not know all the elements of the dataset, we must discuss sampling and experimental design; if the data are not normal we must use other parameters to summarize them, or resort to nonparametric methods; if multiple data are involved, we study the measures of interaction among the variables. Other topics include the study of time-dependent data, and the foundations necessary to avoid ambiguity or paradox. Computational methods (e.g. for curve-fitting) are of particular importance in applications to the sciences and engineering as well as financial and actuarial work.

Certainly the greatest field of overlap with Statistics is 60: Probability.

For experimental design see also 05: Combinatorics.

Some questions on matching data to geometric figures are more properly a question of geometry (especially when there is a unique right answer).

For numerical methods, see 65U05. In particular, this applies to particular curve-fitting algorithms.

Clustering algorithms are related to nearest-neighbor methods in computational geometry.

Other fields with some overlap as seen in the diagram are areas 90 (Operations Research, Game Theory), 93 (Control Theory), 92 (Sciences), 65 (Numerical Analysis), 94 (Communication), 01 (History), 68 (Computer Science), 15 (Linear Algebra)

This is one of the largest areas in the Math Reviews database; many of the subfields listed above are fairly large. Indeed, the sub-areas 62G05 (nonparametric inference; estimation) and 62M10 (time series) are among the largest of the 5-digit areas.
