The following scans are intended to be a resource for classes
like Bluffton's Understanding Numerical Data, in which we try (among
other things) to recognize when data are presented poorly, carelessly, or
misleadingly (either accidentally or intentionally).
- This ad for
Chevy trucks (added 9/6/2001) appeared on the back cover of a
Time magazine in 1992. I could only get a
low-quality scan from a microfiche printout, so this is a
reproduction of the original graph.
- This advertisement for a home
security system company appeared in a Sunday newspaper in spring of '94 or '95.
- This graph was sent in a mailing
soliciting investors in GE Interest Plus.
- This graph appeared on the front page
of Investor's Business Daily.
- This flyer, advertising a brand
of breast pump, was distributed at a conference promoting breastfeeding.
- A closeup of the utterly
meaningless bar graph in the flyer.
I invite others with similar examples to submit them to me (scanned in JPEG
format, if possible). See the contact information on my home page to get in touch
