Olympic medals are an example of an ordinal variable because the categories (gold, silver, bronze) can be ordered from high to low. This is a natural way to represent data because that node-edge-node pattern corresponds perfectly to the subject-predicate-object pattern at the core of a natural human language. Although each value is a discrete number, e.g. , on the other hand, has a standardized order scale, numerical description, takes numeric values with numerical properties, and visualized using bar charts, pie charts, scatter plots, etc. Discrete data involves whole numbers (integers - like 1, 356, or 9) that can't be divided based on the nature of what they are. So anything you can say in words can be represented naturally in a graph. In this case, the data range is 131 = 12 13 - 1 = 12.
