What is the difference between discrete and continuous relationships?

A discrete relationship has unit measurements that cannot be divided.





Example: The sale price of an item, the pairs of shoes sold in a store, the number of babies born this year





A continuous relationship can be infinitely divided into smaller pieces.





Example: The temperature, the length of a board, etc..





Basically, when we measure a continuous relationship, we can have a fraction as a value, such as 1/2 meter. But, in a discrete relationship, it's ';all or nothing';. We count by whole numbers.
