Question 1048207: Numerical Measures of a Quantitative Variable:
Two professors thought at college level STATS. Both had ten students in their respective classes, sections 6980 and 6981. Below please find their evaluations by their students on their overall satisfaction with the class. The students ranked their level of satisfaction from 1 to 5, with 1 being the lowest, and, 5 being, the highest.
6980 1 4 3 4 5 5 4 3 4 5
6981 3 4 5 5 3 4 4 4 3 3
1. What is(are) the mode(s) evaluation score of each professor? What is the mean evaluation score of each professor? What is the median evaluation score of each professor? Can we tell from these numbers which instructor was more popular with the students? And why do you think so?
2. What is the range?
3. What is the Five Number Summary?
4. How about the standard deviation? Do you think we can make some more intelligent statements when we have the standard deviations?
5. Are there variations in the data? If so, how could that affect interpretations? Please be sure to use the data to describe the professors' performance.
