  1. Infographics Overview on What is important Traditional graphs Charts for specific usages Common misleading factors Read also the two books 1

  2. What is represented? Is something misleading? Is something useless? Is something missing? Can other information be added? Fundamental scopes 2

  3. Scale or numeric variables time, age, weight, distance in Kilometers, length, number of children, GDP Nominal or categorical variables country of residence, sex, degreecourse Ordinal variables Likert scale Using them as nominal or scale variables Scales Logarithmicscale Variables

  4. Onenominalvariable • Column plot

  5. Onenominalvariable • Pie chart • Radar graph

  6. Onenominalvariable • Bar plot • Line plot

  7. Onenominalvariable • Area plot • 3D variants

  8. 12 One scale variable 8 4 • Building an histogram • groupingintobins 0 $1,000 $2,000 $3,000 $4,000 $5,000

  9. 8 30 One scale variable 6 20 4 10 2 • Choosing the binscarefully 0 $1,000 $2,000 $3,000 $4,000 $5,000 $1,000 $2,000 $3,000 $4,000 $5,000

  10. One scale variable • Boxplot • Median in black line • Central 50% is in the rectangle • Central 90% isbetweenwhiskers • Extremes are symbols

  11. One scale variable case by case • Use any appropriate nominalvariablegraph

  12. Nominalversus nominal • Side by side • Stacked

  13. Nominalversus nominal • Appropriate 3D variants

  14. Nominalversus nominal • a rare example of a usefulstacked area chart

  15. Nominalversus scale • Boxplot side by side • Histogramoneabove the other

  16. Scale versus scale • Scatterplot

  17. Scale versus scale • Mathematical graph • Regression line

  18. Three scale variables • Surface plot

  19. Three scale variables • Bubble chart • www.gapminder.org

  20. Bubble chart with Google Developers • https://developers.google.com/chart/interactive/docs/gallery/bubblechart • create HTML file which displays graph in browser • insert data manually with Notepad • modify options manually with Notepad • see book for detailed list of instructions • is asked at exam in the open-books practical part • … also graph creating with Excel is asked (see mandatory exercises)

  21. Data map: scale variable

  22. Data map: flow directions

  23. Statsilk software • www.statsilk.com

  24. Time series • Financial chart

  25. Time series

  26. Time series • Gantt chart

  27. Time series

  28. Narrative graph

  29. Narrative graph

  30. Misleadingfactors • Distractibleelements

  31. Misleadingfactors • Elements in the wrongplace

  32. Misleadingfactors • Wrongproportions

  33. Misleadingfactors • Right proportions

  34. Misleadingfactors • Different units of measure

  35. Misleading factors • Not starting from zero

  36. Misleading factors • Two and three dimensional growth

  37. Misleading factors • Two and three dimensional growth

  38. Misleading factors ?
