Assignment Instructions

Answer each question below; submit the file with your answers, including any graphs created, through the assignment link in this course space.

1. Let’s say that you do a study of four different airlines and look at the on-time performance of 7 randomly selected flights. The dependent variable is the number of minutes that a flight is late (so a negative number means the flight is early, and a zero value means the flight was on-time). Here are the (hypothetical) data:

• Use SPSS to produce an appropriate graph that shows the mean performance of each airline. You can copy and paste the output into a Word doc to submit.
• Using a statistics program or the ANOVA helper in your Interactive Stats text, determine whether there is a significant difference in on-time performance (alpha = .05). What is your conclusion: is there one airline that can be considered significantly better than the other three? Be sure to include the ANOVA summary table.
