Unstandardized choropleth maps show data that is basically raw numbers and hasn't really been compared to any other facts or figures and can sometimes be considered a little unreliable. For example, in this map, the images haven't been compared to any other data that has been gathered for the contagiousness of a disease in a land and can therefore be very skewed. If the ability of Lyme disease to spread in this particular area or spot are drastically high, then one might conclude from this data that the entire county or state as a whole, or the "bigger picture" follows this same trend. This can be deducted in the same way if a place had a low rate of being able to contain the spread of Lyme disease and possible eradicate it, then, because the likeness of the sample data is not compared to the whole, a false or partially false movement could be contrived.
