Now for some background about the data set. For the past 12 years I have given my classes as case description of a person with low back pain. I then ask the students to complete a visual analog scale to rate how they perceive the pain of the person in the case. A visual analog scale is a 100 mm line with anchors of no pain and most intense pain. Since it is measured in mm we can treat the data as a ratio level measurement. The students then measure their mark to obtain the pain rating in mm. One purpose in giving this assignment is to demonstrate that different persons will perceive the amount of pain differently. As you can see in the dataset, there were some individuals who scored the pain lower and some who scored it very high. Other purposes are to use the aggregate data for descriptive statistics and inferential statistics.
