Data can be potentially unbounded, if it is not finite data. Unbounded data may be unbounded in one or both directions. Examples of the former are: (coin tosses, discrete data) – the number of heads thrown before the first tail is thrown; (waiting for a bus, continuous data) – the length of time before the bus comes. These are both bounded below but unbounded above. An example of data that is unbounded in either direction is the difference between heights, which can be arbitrarily positive or negative.
