Document Summary
Not existing: variables values as numbers, when we create variables, their values (answer choices) Classifying variables: but not all types of values have the same numerable identity. Are based on how many or what type of level they are on. They simply describe or categorized or name things. Only mathematical property is identity: examples, biological sex: female (1) and male (2, ordinal. Order the data in terms of rank or magnitude. Categories can be arranged from first to last or lowest to highest. Mathematical properties: identity and magnitude: examples, rank in army, interval. Like ordinal variables, they indicate rank, but they also have equal intervals between values. Mathematical properties: identity, magnitude and equal intervals: examples: fahrenheit or celsius, ratio. When variables have everything interval variable do pule a true zero point. Temp might have a value of 0, but that does not mean the absence of temperature. Mathematical properties: identity, magnitude, equal intervals and true zero.
