The purpose of this assignment is to use intermediate visualization software techniques to analyze data and tell the data story.
Launch the "AutomobliesTEMPLATE" twb file. This Tableau file should already be connected to the "Automobiles" Excel file. Ensure that these two files are in the same directory. If the data are not in "AutomobliesTEMPLATE" twb file, use Tableau's data connection tool to connect to the data in the Automobiles Excel file.

Create a new dashboard named "MainDashboard."
Resize the dashboard area so that it occupies the entire available screen. Add the following sheets to the dashboard: MPGScatter, MPGPie, MPGColumn, and MPGTable. Add the following object to the dashboard: Web Page URL:wwwmotortrend.comcarreviews
Resize or move the dashboard panes so that the charts and the web object are conveyed in a meaningful way.

Create a histogram for highway MPG on the MPGHistogram" sheet.
Use the Tableau default bin sizes and display the frequency counts in the top of each column.
Include a cumulative percentage line on the histogram.
Part
Create calculated fields on the MPGTable sheet. Create the following calculated fields in the order as shown below:
Count of highway MPG: Name this field CountMPG"
Average of highway MPG: Name this field AverageMPG"
Median of highway MPG: Name this field MedianMPG"
Standard deviation of highway MPG: Name this field StdevMPG"
Coefficient of Variation CV of highway MPG Note: CV standard deviationaverage Name this field CoeffVariationMPG"
Create a calculated field to indicate the skew of each category. Name this field ShapeMPG."
Note that if AverageMPG is less than MedianMPG, "leftskewed" should be displayed.
If AverageMPG is equal to MedianMPG, "normal" should be displayed.
If AverageMPG is greater than MedianMPG, "rightskewed" should be displayed.
Hint: The IF THEN, ELSE IF and ELSE statements should be helpful here.
Once the aforementioned calculated fields are created, revise the MPGTable to include the calculated fields in the columns, and Vehicle Size in the rows. Specifically, the columns from lefttoright should be: Vehicle Size, ShapeMPG, CountMPG, AverageMPG, MedianMPG, StdevMPG, and CoeffVariationMPG. Mark the chart by color based on ShapeMPG.
Part
Create another dashboard named "MPGStatsDashboard."
Resize the dashboard area so that it occupies the entire available screen. Add the following sheets to the dashboard: MPGHistogram and MPGTable.
Resize or move the dashboard panes so that the charts are conveyed in a meaningful way.
Part
Using the Tableau story tool, create a Tableau data story named MPGStory that summarizes the statistical analysis:
Include the following sheets in the Tableau story: MPGHistogram and MPGTable.
Provide a word detailed narrative discussion for each of these two sheets in the story. Input the narrative into the Tableau storyboard.
Add the "MainDashboard" at the end of the Tableau story. Rather than summarizing the data in the dashboard, provide a word discussion of the advantages of using dashboards in analytics. Input the narrative discussion into the Tableau storyboard.
