2. Fan chart (time series) - Wikipedia

   en.wikipedia.org/wiki/Fan_chart_(time_series)

   The split normal density is completely characterized by three parameters, the mode, variance and skewness. Therefore, the fan chart ranges depend on these parameters only. [4] [5] [6] and [8] In a central bank that employs inflation targeting, the three moments of the inflation forecast distribution are determined as follows: The mode.

3. Range mode query - Wikipedia

   en.wikipedia.org/wiki/Range_mode_query

   Any data structure using cells of bits each needs (⁡ ⁡ (/)) time to answer a range mode query. [3]This contrasts with other range query problems, such as the range minimum query which have solutions offering constant time query time and linear space.

4. Mode (statistics) - Wikipedia

   en.wikipedia.org/wiki/Mode_(statistics)

   In a formula, median ≈ (2 × mean + mode)/3. This rule, due to Karl Pearson, often applies to slightly non-symmetric distributions that resemble a normal distribution, but it is not always true and in general the three statistics can appear in any order. [5] [6] For unimodal distributions, the mode is within √ 3 standard deviations of the ...

5. Median - Wikipedia

   en.wikipedia.org/wiki/Median

   If, say, 22% of the observations are of value 2 or below and 55.0% are of 3 or below (so 33% have the value 3), then the median is 3 since the median is the smallest value of for which () is greater than a half. But the interpolated median is somewhere between 2.50 and 3.50.

6. Normal distribution - Wikipedia

   en.wikipedia.org/wiki/Normal_distribution

   The general form of its probability density function is [2] [3] = (). The parameter ⁠ μ {\displaystyle \mu } ⁠ is the mean or expectation of the distribution (and also its median and mode ), while the parameter σ 2 {\textstyle \sigma ^{2}} is the variance .

7. Central tendency - Wikipedia

   en.wikipedia.org/wiki/Central_tendency

   the middle value that separates the higher half from the lower half of the data set. The median and the mode are the only measures of central tendency that can be used for ordinal data, in which values are ranked relative to each other but are not measured absolutely. Mode the most frequent value in the data set.

9. 68–95–99.7 rule - Wikipedia

   en.wikipedia.org/wiki/68–95–99.7_rule

   In statistics, the 68–95–99.7 rule, also known as the empirical rule, and sometimes abbreviated 3sr or 3 σ, is a shorthand used to remember the percentage of values that lie within an interval estimate in a normal distribution: approximately 68%, 95%, and 99.7% of the values lie within one, two, and three standard deviations of the mean ...
