A dot distribution map (or a dot density map or simply a dot map) is a type of thematic map that uses a point symbol to visualize the geographic distribution of a large number of related phenomena. Dot maps are a type of unit visualizations that rely on a visual scatter to show spatial patterns, especially variances in density.
A spatial distribution in statistics is the arrangement of a phenomenon across the Earth's surface and a graphical display of such an arrangement is an important tool in geographical and environmental statistics. [1] A graphical display of a spatial distribution may summarize raw data directly or may reflect the outcome of a more sophisticated ...
Distribution (mathematics) Distributions, also known as Schwartz distributions or generalized functions, are objects that generalize the classical notion of functions in mathematical analysis. Distributions make it possible to differentiate functions whose derivatives do not exist in the classical sense. In particular, any locally integrable ...
Species distribution. A species range map represents the region where individuals of a species can be found. This is a range map of Juniperus communis, the common juniper. Species distribution, or species dispersion, [1] is the manner in which a biological taxon is spatially arranged. [2]
Electric power distribution is the final stage in the delivery of electricity. Electricity is carried from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 33 kV with the use of transformers. [1]
A discrete probability distribution is the probability distribution of a random variable that can take on only a countable number of values [15] ( almost surely) [16] which means that the probability of any event can be expressed as a (finite or countably infinite) sum: where is a countable set with .
Cartogram. Mosaic cartogram showing the distribution of the global population. Each of the 15,266 pixels represents the home country of 500,000 people – cartogram by Max Roser for Our World in Data. A cartogram (also called a value-area map or an anamorphic map, the latter common among German-speakers) is a thematic map of a set of features ...
In a distribution map, paths leave the origin with a width proportional to the total of several destinations, then divide as routes "distribute" toward each destination. Designing distribution maps requires some care and craft in drafting the flow lines so they divide with proper widths, and at smooth curving angles.
A dasymetric map (from Greek δασύς dasýs 'dense' and μέτρο métro 'measure') is a type of thematic map that uses areal symbols to visualize a geographic field by refining a choropleth map with ancillary information about the distribution of the variable.
Triangular. In probability theory and statistics, the triangular distribution is a continuous probability distribution with lower limit a, upper limit b, and mode c, where a < b and a ≤ c ≤ b .
