Week 1 Practice Worksheet Prepare a written response to the following questions. Chapter 1 1. Explain and give an example for each of the following types of variables Nominal categorizing people or things with no meaningful order to them. Examples would be classifying people by gender, religion, or which hand (left or right) they are dominant with Ordinal Comparison or evaluation of something to different values on a scale. Comment cards in restaurants use this. how well did we serve you today with the numbers 1-5 appearing under the question, 1 being very bad and 5 being very good. Interval Number scales that retain the same interpretation throughout their entirety. An example would be the weight of something measured in pounds. Ratio scale A scale that is compromised of nominal, ordinal, and interval scales all in one. It provides the category of something, and that something is ordered numerically, and those numbers retain their interpretation entirely. An example would be money Continuous A variable that can be any value between its minimum and maximum value. An example of this would be the weight class for professional fighters. Discrete The opposite of continuous variables. Discrete cannot take on any value between the min and max values. For example, if we flip a coin and count how many times we get heads vs tails, we can never end up with 2.5 heads. Quantitative a variable that is measured on a numeric scale. An example would be shoe size, or how much a person weighs. Qualitative a variable that is categorical and labeling. The ethnicity of a person, or the breed of a dog would be examples of this. 2.
