What are the disadvantages of using a choropleth map to present data?

Disadvantages of Choropleth Maps

• They give a false impression of abrupt change at the boundaries of shaded units.
• Choropleths are often not suitable for showing total values.
• It can be difficult to distinguish between different shades.

Is blood type continuous or discrete?

Blood type is not a discrete random variable because it is categorical. Continuous random variables have numeric values that can be any number in an interval. For example, the (exact) weight of a person is a continuous random variable. Foot length is also a continuous random variable.

Is age discrete or continuous?

Age is measured in units that, if precise enough, could be any number. Therefore the set they come from is infinite. For example, someone could be 22.32698457 years old or 22.32698459 years old. We could be infinitly accurate and use an infinite number of decimal places, therefore making age continuous.
