2. Mode (statistics) - Wikipedia

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

   Mode (statistics) In statistics, the mode is the value that appears most often in a set of data values. [1] If X is a discrete random variable, the mode is the value x at which the probability mass function takes its maximum value (i.e., x=argmaxxi P (X = xi)). In other words, it is the value that is most likely to be sampled.

3. Univariate (statistics) - Wikipedia

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

   Univariate is a term commonly used in statistics to describe a type of data which consists of observations on only a single characteristic or attribute. A simple example of univariate data would be the salaries of workers in industry. [1] Like all the other data, univariate data can be visualized using graphs, images or other analysis tools ...

4. 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:

5. Central tendency - Wikipedia

   en.wikipedia.org/wiki/Central_tendency

   the arithmetic mean of the first and third quartiles. Quasi-arithmetic mean A generalization of the generalized mean, specified by a continuous injective function. Trimean the weighted arithmetic mean of the median and two quartiles. Winsorized mean an arithmetic mean in which extreme values are replaced by values closer to the median.

6. Unimodality - Wikipedia

   en.wikipedia.org/wiki/Unimodality

   In statistics, a unimodal probability distribution or unimodal distribution is a probability distribution which has a single peak. The term "mode" in this context refers to any peak of the distribution, not just to the strict definition of mode which is usual in statistics. If there is a single mode, the distribution function is called ...

7. Normal distribution - Wikipedia

   en.wikipedia.org/wiki/Normal_distribution

   A normal distribution or Gaussian distribution (also known as the "bell-shaped curve") is a concept used in probability theory and statistics. [ 2 ] The normal distribution concept is applied in numerous disciplines, including education, psychology, economics, business, the sciences and nursing.

8. Five-number summary - Wikipedia

   en.wikipedia.org/wiki/Five-number_summary

   The five-number summary is a set of descriptive statistics that provides information about a dataset. It consists of the five most important sample percentiles: the sample minimum (smallest observation) the lower quartile or first quartile. the median (the middle value) the upper quartile or third quartile. the sample maximum (largest observation)

9. Median graph - Wikipedia

   en.wikipedia.org/wiki/Median_graph

   The median of three vertices in a median graph. In graph theory, a division of mathematics, a median graph is an undirected graph in which every three vertices a, b, and c have a unique median: a vertex m (a, b, c) that belongs to shortest paths between each pair of a, b, and c. The concept of median graphs has long been studied, for instance ...
