Stem and leaf plot

A stem and leaf plot is a numerical display of the distribution of a variable. The information is written to show that the last digit is the leaf and the rest of the numbers in front are the stem. The one above is just an example on how stem and leaf plots work. http://www.webquest.hawaii.edu/kahihi/mathdictionary/images/stem_leaf_graph1.gif

Box plot

A box plot is an easy way to graphically depict groups of numerical data through their 5 number summaries. The image above shows how the typical box plot works. http://www.physics.csbsju.edu/stats/box2.html

Histogram

A histogram is a diagram consisting of individual bars who has different values. The values are dependent on the y-axis and the x-axis. The y-axis determines how high the bars will rise, while the x-axis is what we are measuring. The map shows the hours of delay in traffic per major city. http://www.coolinfographics.com/blog/2010/2/9/city-population-shift-maps.html

Parallel coordinate graph

Parallel coordinate graphs show a series of data and values. It shows many types of variables and that are displayed on their own axis. These axis are vertical and can potentially be linked to different values. http://www.ats.ucla.edu/stat/mult_pkg/perspective/v18n2p15.htm

Triangular plot map

A triangular plot map is a way to plot three different variables which have the same purpose. It shows the ratios of the three variables on an equilateral triangle. The picture shows how each corresponding major parties would win over majority in Parliament. http://kelseyherritt.blogspot.com/2011/04/triangular-plot.html

Wind rose map

A wind rose map measures the wind speed and direction of the wind in a given area. The map above gives the wind quality in Maine. The key shows that in black it has wind speeds over 22 mph. http://www.maine.gov/dep/air/meteorology/Windrosehome.html

climograph

This climograph is of the United States over a whole calendar year. A climograph is a graphical depiction of the monthly precipitation and temperature conditions for a selected place. This one shows the climograph of Boulder, Colorado. http://www.colorado.edu/geography/extra/geogweb/manitousprings/intro/page2.html

population profile

Population profiles or population pyramids are commonly used to show the trends in population statistics over time. The first pyramid shows that Kenya has rapid growth. They have a very young population with high fertility rates and high death rates among their older population. http://albanesemapcatalog.blogspot.com/2011/04/population-profile.html

scatter plot

Scatterplots are used to display two or more sets of data using cartesian points. Correlations are formed when you can see a pattern between the points. This scatter plot shows the correlation between the wife's age and the husband's age. http://tb04fmapcatalog.blogspot.com/2011/04/scatterplot.html

index value plot

Index value plots show discrepancies between different datas. In this map you can see how countries like France and US have similar correlations, while Germany has a significantly higher curve. http://sosiekaesmapcatalog.blogspot.com/2012/07/index-value-plot.html

Lorenz curve

A Lorenz curve represents a probability distribution of statistical values, and often shows the degree of inequality that exists between two variables. For instance, in this Lorenz curve, the distribution of income is illustrated in reference to the percent of the population. http://mapanalysis.blogspot.com/2011/04/lorenz-curve.html

bilateral graph

A bilateral graph displays two or more related sets of data on that same graph. This graph can be a line graph, bar graph, or some other type of graph. This map shows the comparison of two variables. It shows "Forced" Preference for Communism versus Fascism. http://chasesmaps.blogspot.com/2010/11/bilateral-graph.html

nominal area choropleth map

A nominal area choropleth map is a thematic map that displays areal data. These maps use different colors or patterns to distinguish between certain areas or regions. The data that is represented is nominal data, meaning there is no ranking order for each category, so therefore a rainbow of different colors is many times used. This map shows the minority groups with highest percent of state population. http://tomsmapcatalog.blogspot.com/2010/04/nominal-area-choropleth-map.html

unstandarized choropleth map

Different color shades are used in unstandardized chloropleth maps to represent data. These types of maps are not aerially averaged, nor do they use numerical data or ratios. This map shows deaths per 1,000 live births in Australia. http://eps.mq.edu.au/courses/GEOS219/choropleth.htm

Standarized choropleth map

Standardized chloropleth maps calculates the population per square mile so that the distribution of people can be compared. The shading shows the relative population distribution in each state. http://emilyness16.blogspot.com/2012/03/standardized-choropleth-maps.html

Univariate choropleth map

Univariate choropleth maps are used to show a single variable. The following map is showing the percentage of individuals that are living in poverty, by county. http://fishermaniacsmaps.blogspot.com/2012/04/univariate-choropleth-maps.html

bivariate choropleth map

A bivariate choropleth map shows two variables on the same map. A bivariate map may consist of line features, polygon features, or point features. The map above is an bivariate map depicting the median house values in counties all over Ohio. http://proceedings.esri.com/library/userconf/proc99/proceed/papers/pap171/p171.htm

unclass choropleth map

An unclass choropleth map uses a frequency curve that varies the shading or color intensity from the lowest to the highest specified value. The map above shows the 2004 presidential election votes. http://mapblogsven.blogspot.com/2008_11_01_archive.html

Class Choropleth map

Class choropleth maps shows how dense something is by using a bar portraying a different color. In the map above it shows how dense the population is in each location of the United States. http://www.survivalblog.com/2011/07/letter_re_the_thinning_of_the.html

range graded proportional circle map

Range graded proportional circle map represents circles which are made in relation to range of data. The map shows how many American Indians are in the the western United States. http://aronhotalen.blogspot.com/2010/04/range-graded-proportional-circle-map.html

continuously variable proportional circle map

Continuously variable proportional circle map portrays data is being depicted by using dots that are proportional in scale and location of the information being represented. In this map it shows a map of people killed in road accidents in Europe. http://irvinecatalogs.blogspot.com/2011/07/range-graded-proportional-circle-map.html

DOQQ map

DOQQ is a satellite imagery that narrowly defines a region. This image is a DOQQ of Washington D.C. http://en.wikipedia.org/wiki/Digital_orthophoto_quadrangle

DEM map

DEM,digital elevation model,is a map that shows a 3D map of the Earth's, or any surface, terrain. This map shows the terrain of Sturgis, South Dakota. http://albanesemapcatalog.blogspot.com/2011_04_01_archive.html
