Unstandardized Choropleth Map

http://bigthink.com/strange-maps/308-the-pop-vs-soda-map

Unstandardized maps are obviously choropleth maps that are unordered, in other words, they display information cannot be ranked; no category is higher or lower than another. I found this map to be interesting because of the topic that it measures is pretty funny and that is generic names for soft drinks. The term “pop” clearly dominates the map and takes over half of the country in the north. The term “coke” is used in the majority of the south excluding all of California and Arizona, and the southern half of Nevada. California, Arizona, southern half of Nevada, and the northeast corner of the country call soft drinks soda. In addition, there is the other category that is very sparse in the country which only triggers my curiosity on what else could you possibly name a soft drink?

Isopleth

An isopleth is a contour line that connects points that have an equal value of a certain variable at a certain time and in a certain area. This variable can be many things including temperature and population. Isopleths also show a continuous distribution of data. This isopleths shows the hydrogen ion concentration as pH from measurements made at the field laboratories in 1998. The highest levels of field pH are represented by shades of green with the darkest shade being the greatest, and the shades of orange represent the lowest levels of field pH with the darkest being the least. The western side of the United States presents the highest levels of field pH, while the eastern side of the United States presents the lowest levels of field pH.

Correlation Matrix

The correlation matrix is a matrix that displays the relationship between all pairs of data sets.  These relationships range from -1 to 1 with 1 representing the greatest correlation and -1 representing the least correlation. This table represents 10 things GNP per capita, trade, power, stability, freedom of opposition, foreign conflict, U.S. agreement, defense budget, Percent GNP for defense, and international law acceptance. This shows that the greatest correlation is between GNP per capita and trade. The least correlation is between freedom of opposition and percent GNP for defense.

Nominal Area Choropleth Map

Nominal Area Choropleth Maps are thematic maps that show areal data with the use of colors to distinguish different areas. The only data that is represented in these maps are nominal data. This map shows the House of Representatives Election map of 2008. This map displays that the democrats are the majority party with 255 votes and gained 20 seats. The Republican party was the minority and obviously lost 20 seats with the Democrats victory. There is no obvious trend to which sections of the country are Democratic or Republican. 

Box Plot

A box plot is a graphic representation of data in the shape of a rectangle. In addition, it has extensions, which indicate the maximum and minimum values, and have markers showing the median, and the first and third quartiles. This box plot is comparing the energy output of four machines. The results show that the machines output has a significant effect on energy in accordance to location and variation. Machine 3 has the greatest energy response with an output of about 72.5. Machine 4 has the lowers energy response with an output of about 67.5. 

Scatterplot

A scatterplot is best for showing the extent of a correlation and making sense of that correlation. If the y-axis variable increases as the x-axis increases the correlation is positive. If the y-axis variable decreases as the x-axis variable increases or vice-versa, the correlation is negative. If there is no correlation, between the variables the points appear randomly placed on the coordinate plane. This scatterplot displays the correlation between the price of a diamond and the size of diamonds in carats.  The trend shows that as the size of the diamond increases in carats, the price also increases.

Univariate Choropleth Map

http://www.dailyyonder.com/poverty-rate-jumps-rural-america/2009/11/23/2466

Univariate choropleth maps, like the title suggests, only displays a single set of data. This maps data set is poverty in rural America in 2008. The highest poverty percentage is represented by red and then fades toward the average, and the lower percentage starts at a pale green and progresses to a dark green color. The trend in this map is that counties with higher rates of poverty tend to be in the south and northwest, and counties with lower rates of poverty tend to be in the north.
