Describe the world
Our process begins by describing the world in some way. We make a series of observations of some type of object or phenomena. Each observation has one or more qualities, commonly called attributes. Attributes can be thought of in a couple of ways, names or numbers.
Names[edit | edit source]
Names are quite common, and are usually distinguished by different text. For example, we might have different names for a quality we call color, which could include red, orange, and blue.
Numbers[edit | edit source]
Numbers may contain more detail than names. For example numbers can tell us how things are ordered, or how large they are when compared with one another. We will see these types of measurement referred to as Ordinal, meaning ordered, and Interval, meaning there is a regular distance from one number to the next (hence magnitude).
