Invalid View → Wrong Conclusions
• Over-simplified view to complex data can lead to
wrong conclusions and crucial mistakes
– Nearly all real-world data is complex!
– Most business reports are too simple
• Histograms, pie charts, average trends, ...
– Should be used only for 1-dimensional data
• Scatter plots, bubble diagrams, ...
– Can view 2-3 dimensional data, but often messy
• What if my data has 3+ columns?
