Discrete data

Here are the results from a recent survey about the number and type of pets each member of a class has.

Table for type of pets: Dogs, 12. Cats, 14. Fish, 2. Rats, 6. Snakes, 1.

This data is discrete because it is made up of whole numbers. For example, you cannot have half a dog or half a cat.

European shoe sizes are another example of discrete data. You can be a size 36, or a size 38, but you cannot be a size 36.1 or a 38.3.
