(12) Explain and give an example for each of the following types of variables:
A) equal interval- A variable whose value is not known and can take on different values. For example 0 degrees Celsius or Fahrenheit (0 degrees Celsius does not mean there is no temperature but it is different from 0 degrees Fahrenheit.)
B) rank order- variables that are individual observations that can be put into order from smallest to largest, even though the exact values are unknown. An example of this would be shirts, small, medium and large shirts.
C) Nominal- variables which are also called categorical variables. They classify observations into a small number of categories. Examples are 1) "types of property" can include houses, condos, Co-ops, or bungalows. Another example 2) Gender or race
D) Ratio Scale- is measured data with a zero point and provides information relative to an absolute zero. An example of this is a person's weight. The scale starts at 0 and when you step on it, the amount goes up starting from 0 to the amount of weight on it. (It has to start at 0).
E) Continuous- variables that are numeric and can be any number (positive or negative). Examples of a continuous variable can be red blood cells, body temperature, or any other continuous readings such as body weight.
