    Analyze > Distribution, Rows > Hide and Rows > Exclude, Graph > Pareto Plot, dynamic plot linking, Rows > Data Filter, Analyze > Fit Y by X (Oneway), and Graph > Graph Builder

    Statistical/Graphical Tools Used:

    Histogram, summary statistics, bar chart and frequency distributions, Pareto Plot, pie chart, and box plots.

  • Baggage Complaints

    Descriptive Statistics and Time Series Plots

    Compare the baggage complaints for three airlines: American Eagle, Hawaiian, and United. Using descriptive statistics and time series plots, explore differences between the airlines, whether complaints are getting better or worse over time, and if there are other factors, such as destinations, seasonal effects or the volume of travelers that might affect baggage performance.
