Analyzing Rank Order Data
Message posted by Jim V. on April 13, 2000 at 12:00 AM (ET)

I am looking for a simple method for analyzing rank order data. Respondents are asked to rank the top five items (1 most important and so on) out of a total of ten items. Any sugggestions.
Please keep it in laymen terms.


READERS RESPOND:
(In chronological order. Most recent at the bottom.)

Although I would need to know a bit more about your design to indicate the most appropriate statistical proceedure, I can make two suggestions:

(1)a Spearman's rank-order correlation (rho) looks at the relationship between a variable which has received a randking and a continuous variable (e.g. could be used to find the relationship between a teacher's ranking of students in her class to the students' actual IQ scores).

(2)a Kendall's rank order correlation (tau) can be used when both variables are ranked (e.g. used to find a correlation between the rankings two judges gave participants in figure skating competition)

Let me know if these were not exactly what you needed.

If you take the results of rank of each item given by all the resondents and then average them, you can get an average rank for each team and list them in order. This is called the "Nominal Group Technique" and is a widely accepted technique for such things as ranking performance, scholarship applications, etc.
