Analysis of Variance One and Two Way ANOVA SPSS File Report

 Analysis of Variance One and Two Way ANOVA SPSS File Report

Using SPSS, this week’s assignment focuses on using analysis of variance ANOVA: both one-way and 2-way with interactions. One-way ANOVA allows researchers to investigate the difference of the means for 3 or more groups. Two-way ANOVA with interactions is used to investigate the difference in the groups of the two factors and their interaction.

To complete the assignment:

• Download and review the ANOVA assignment instructions.docx
• Using the airline satisfaction ANOVA.sav dataset to conduct one-way and 2-way ANOVAs to answer the questions below, Type your responses in a Word document:

(Note: Be sure to use the numeric variables for Class, Flight Cancelation and Age Range. String variables cannot be used in ANOVA calculations.)

1. Does satisfaction differ for different classes (Business, Eco, and Eco Plus)? Include the output from SPSS. Which class is most satisfied? Which class is the least satisfied?
2. Using a two-way ANOVA, and the factors Flight Cancelled and Class, determine if satisfaction differs if a flight is canceled.

• • If so, are passengers more satisfied if the flight is not canceled?
  • Determine if satisfaction differs by Class. If so, which class is the most satisfied and which is least satisfied? How does this result compare with the result in question 1?
  • Is there a significant interaction between Flight cancellation and Class? If so, how does this affect satisfaction?
  • Include your output tables from SPSS in your report.

1. Using a two-way ANOVA and the factors Flight Cancelled and Age Range, determine if satisfaction differs if a flight is canceled.
   • If so, are passengers more satisfied if the flight is not cancelled?
   • Determine if satisfaction differs by Age Range. If so, which age range is the most satisfied and which is least satisfied?
   • Is there a significant interaction between Flight Cancellation and Age Range? If so, how does this affect satisfaction?
   • Include your output tables and plots from SPSS in your report.
2. Knowing the results of the one-way ANOVA concerning class and the results for the two-way ANOVAs concerning flight cancellation, class and age range, recommend marketing actions that could be implemented to specifically address these results that would increase satisfaction.
