Homework Three



We discussed the Delphi method. The questions below will give a more in-depth understanding of the Delphi method. Post the answers on your blog.



1. If your question was one of those that the class used the Delphi method on, find the median and the range of the middle 50% of the responses. Using a graphics editor of your choice (even paint works for this), make a graph that is analogous or similar to the one in the lecture notes, showing the total range, middle 50% range, and median. If your question was not discussed in class, then (1) figure out a way of saying the question that will hopefully work well when we apply the Delphi method to it in class, and (2) explain why you designed the question the way you did.

My question was one of those that the class used the Delphi method one the question was when commercial airplanes will be ten time faster. We recorded students’ prediction on the board. Then I asked some of my classmates about their predictions. Then we recorded a new predication based on the discussions that we had which almost was the same.

2. Read up on the Delphi method on the Web (or the library). Explain how the process that we went through in class differs from the process as described in the sources you found.

Delphi Method: we use it to explore an issue with a distributed group of people. In this method we define the problem that we want to work on, then we give everyone the problem, then we collate the responses, then we give everyone the collation, and finally we repeat as necessary. i think we went through the process very well.

3. Based on what you can find about the Delphi method, what shortcomings, risks, or other weaknesses do you see for the process that we followed in class? Also do you see a way to fix some of these?

I think if we have the questions before the class it would be better, we could read about the questions from the internet or ask about them which will allow us to have stronger discussions.
