+# About
+
+"Statistics" is a large and complex subject with many aspects.
+
+Some aspects were touched on in the [`Randomness`][randomness] concept, which is a separate but related subject.
+
+At its simplest, statistics can involve ways to summarize an iterable collection of data in a single value.
+Newcomers to Julia may be surprised at how few functions are built in to the language by default:
+
+- [`sum`][sum], to add up numbers.
+- [`min`][min] and [`max`][max] to get the extreme values of the given parameters.
+- [`extrema`][extrema] to get the (min, max) tuple of an iterable.
+- [`length`][length], to count all values.
+- [`count`][count], to count only values meeting some criterion.
+
+```julia-repl
+julia> v = collect(1:0.2:3)
+11-element Vector{Float64}:
+ 1.0
+ 1.2
+ ... # display truncated
+ 3.0
+
+julia> mean(v)
+2.0
+
+julia> std(v)
+0.66332495807108
+
+julia> var(v)
+0.44000000000000006
+
+julia> extrema(v)
+(1.0, 3.0)
+
+julia> length(v)
+11
+
+julia> min('g', 'a', 'c')
+'a': ASCII/Unicode U+0061 (category Ll: Letter, lowercase)
+
+julia> count(isodd, 1:5)  # 1, 3, and 5 are odd
+3
+```
+
+This limited set of functions is a deliberate decision to minimize bloat in base Julia by moving other functions out to a cascade of other modules and packages.
+
+## The `Statistics` module
+
+As part of the standard library, [`Statistics`][statistics] is likely to be pre-installed, so just needs `using Statistics` added to the top of the program to bring it into the namespace.
+
+This module contains the next tier of common functions, which are likely to be widely used by a subset of programmers.
+
+Many of the functions in `Statistics` assume some background knowledge of the subject.
+The simplest examples include:
+
+- [`mean`][mean], which many people would call the average (same result as `sum / length`).
+- [`median`][median], the middle value after sorting.
+- [`std`][std], [standard deviation][stddev]: a measure of how widely spread the values are.
+- [`var`][var], variance: the square of `std`, which is generally quicker to calculate.
+
+Each function tends to have various options, and there are _many_ more functions, so check the [documentation][statistics] if interested.
+
+## Other packages
+
+As you might expect, statistics is a big use-case for Julia, and there many available packages to support more specialized work.
+
+The JuliaStats group helpfully maintain an [online list][juliastats].
