Module 7 - Discussion: Formulating Research Questions In a research project, the researcher normally has a research question in mind and then develops a research methodology. Thé methodology includes such things as determining the type of data that will be needed to address the question, how the data will be collected, and how the data will be analyzed. Due to time constraints, you will take a different approach to developing a research question, You will be given data that has already been collected and asked to develop a possible research question from the data. For this discussion activity, open the StatCrunch file, Southwest Airlines Data. The variables are explained within the file description. Use the file is in the course StatCrunch group (Enrolment Instructions D) This discussion is a lead-in to the t-Test Course Project that you will be working on in the next module. You will be asked to do something similar to this activity for your project and also asked to collect and analyze the data. Look at the description of the variables in the file and the variables themselves. Then develop a "research question" that can be answered using a one- or two-sample t-test and confidence interval that might be interesting to explore using this data set. Some examples are: . Is the average delay time longer at Midway than at Dallas? ·Is the average taxi time longer at Houston than at Dallas? Develop your own research question. Be creative! Do not use one of the questions above or the ones your classmates post. Try to find something that might be interesting to you. After you post your question, also indicate the techniques you would use to answer it. For this Discussion Board activity, you don't need to analyze the data. You only need to develop a research question. You should post it on the discussion board no later than the 4th day of the week. By the end of the week, return to the discussion, review the postings of other students, and comment on at least two of them (lmage retrieved from flickr: https//secure hotos/4642310 5N03/5056601949

Explanation / Answer

One of the most intriguing questions for this project can be related to the time taken for maintainance by the airplane between two consecutive flights. Running an airplane is one of the riskest and the most expensive jobs in the world. Most flight airlines thus struggle to even break even, let alone turn a profit. So minimizing maintainance time is one of the most priortizing issue for any airplane vendor.

So the report question can be : Is the average maintaince time and cost for an airplane higher at Houston than at Dallas? Or between any two cities of your choice. For more than two cities comparison we can use ANOVA techniques for comparison.

The techinique we would use to answer is the hypothesis testing using t test.
