Bilateral Graph

A bilateral graph is one in which there are two variables being measured and graphed as well as where these two variables over lap. This graph shows adults who had implants put either into one ear (right or left) or both ears; and who was able to hear better e,6, and 8 months later. It is shown clearly in this graph that adults who had the implants put into both of their ears were hearing on much higher levels than those who only received one.

Nominal Area Choropleth Map

A nominal area choropleth map displays data with ungraded color patterns which helps the reader with recognition of areas of interest. For example race a good topic to be shown within a nominal area choropleth map. The race being used within this map is the Latino and/or Hispanic race and it is broken down by county within the 2009 census. South Florida near Miami has the highest percentage of Latino/Hispanics, which I believe is to be known as Dade county.

Unstandardized Choropleth Map

Unlike a standardized choropleth map in this unstandardized choropleth we can see it is not averaged by any sort of percentages or measurements. By this map we are able to see the total fertility rates of the entire world between the years of 2000 to 2005. Of all of the seven continents (six being shown) we are able to see that Africa is the most fertile of all.

Standardized Choropleth Map

This standardized choropleth map shows the percent of the Canadian population under the age of 14 in the 2006 census. Standardized choropleth maps are areally averaged and just as this map they can be presented in many different ways. They allow comparison of distribution amoungst areas as well.

Univariate Choropleth Map

This picture of a Univariate Choropleth map shows the harvested acres of corn for grain in 2002. We can see that many areas in the north have between 100,000-149,000 acres and with some areas having over 150,000 acres. This would be considered to be a univariate choropleth map because it is a single data set displayed over one given areas.

Bivariate Choropleth Map

A Bivariate Choropleth Map uses color to solve a problem of representation in four dimensions. This bivariate choropleth map offers several sequential and diverging color schemes, automatic or manual classification as well as a scatter plot so that we can view the relationship between attributes.

Unclassed Choropleth Map

The unclassed choropleth map is the technique that assigns shading proportional to the data values so that these choropleth mapsto not have to classify data. Cartographers claim that with this method they lose the ability to direct the message of communication. There are five classes used on on an equal bin interval classification scheme.
