Module 6: Data Classification

Module 6 went through the different data classifications and compare and contrast the different classifications.  It also helped give experience on how best to symbolize or choose color schemes.

The map for this module displays four different data classification of the population of Escambia over the age of 65.  To display all of the types of data classification, three more data frames were added.  For each data frame I selected to show the data by quantities and changed how they were classified.  I selected natural breaks, standard deviation, equal interval, and quantiles for each data frame.  

I tried to pick a color scheme that would show the low classes and allow me to compare the data across the four maps.  I enjoyed how this lab allows you to see how data is classified can change what the data shows.  One map makes it seem like there is a high population of those 65 and older in one census tract, while another shows there is less.  Data classification can be used to show what you want to show and you hope people only try to show the true data.
