Sure-fire ways to spoil data, Part II

How to ruin your data continued ...

Last time, we took a look at six of Howard Wainer’s golden rules to ruin data. To double your pleasure, we decided to explore six more:

7. Emphasize the trivial (ignore the important). If you want to explain how salaries have changed over time based on education and gender, segregate this information into two separate charts for women and men.

8. Jiggle the baseline. Add small values to larger ones by stacking them together. Even the smartest of bystanders will not notice the changes in the smaller values.

9. Austria first. Always sort your chart in alphabetical order and never by analytical content. If someone complains, defend yourself by saying that it is easier to locate a specific entry that way."    (Continued via Me, myself and BI)    [Usability Resources]
