Paper Outline: You are to “pretend” and put yourself into the following context.

2. Introduction, company information, consulting firm information.Your story, your interest.
3. Data Understanding, what the data set represents and used for.
4. Data Preparation, how the data set was “cleaned up,” file preparation, missing data removal.
5. Discussion of data dictionary. Include URL of data location.
6. Discussion of correlation matrix, explain any “interesting” correlations.
7. Discussion of scatter plots, and why you selected the specific variables to use.
8. Discussion of PivotTables, and why you selected the specific variables to use.
9. Discussion of bar charts, and why you selected the specific variables to use.
10. Discussion of histograms, and why you selected the specific variables to use.
