2. Central tendency - Wikipedia

   en.wikipedia.org/wiki/Central_tendency

   the arithmetic mean of data values after a certain number or proportion of the highest and lowest data values have been discarded. Interquartile mean a truncated mean based on data within the interquartile range. Midrange the arithmetic mean of the maximum and minimum values of a data set. Midhinge the arithmetic mean of the first and third ...

3. Log-normal distribution - Wikipedia

   en.wikipedia.org/wiki/Log-normal_distribution

   Comparison of mean, median and mode of two log-normal distributions with different skewness. The mode is the point of global maximum of the probability density function. In particular, by solving the equation ( ln ⁡ f ) ′ = 0 {\displaystyle (\ln f)'=0} , we get that:

4. Shewhart individuals control chart - Wikipedia

   Individuals and moving range control chart; Originally proposed by: Walter A. Shewhart: Process observations; Rational subgroup size: n = 1: Measurement type: Average quality characteristic per unit: Quality characteristic type: Variables data: Underlying distribution: none: Performance; Size of shift to detect: ≥ 1.5σ: Process variation ...

5. 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.

6. Mode (statistics) - Wikipedia

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

   Like the statistical mean and median, the mode is a way of expressing, in a (usually) single number, important information about a random variable or a population. The numerical value of the mode is the same as that of the mean and median in a normal distribution, and it may be very different in highly skewed distributions.

8. Median - Wikipedia

   en.wikipedia.org/wiki/Median

   The median of a symmetric distribution which possesses a mean μ also takes the value μ. The median of a normal distribution with mean μ and variance σ 2 is μ. In fact, for a normal distribution, mean = median = mode. The median of a uniform distribution in the interval [a, b] is (a + b) / 2, which is also the mean.

9. Range mode query - Wikipedia

   en.wikipedia.org/wiki/Range_mode_query

   The mode of the block can be retrieved from . By Theorem 1, the mode can be either an element of the prefix (indices of [:] before the start of the span), an element of the suffix (indices of [:] after the end of the span), or .
