Here’s one of two related metrics where I don’t believe it’s possible to draw any conclusions of any sort–the number of illustrations per blog. After all, many excellent blogs have no illustrations at all.

For the three-month period studied in Public Library Blogs: 252 Examples,  I counted a total of 4,691 illustrations in all. Here are the quintiles:

• Q1: Most illustrations: From 24 to 814 illustrations.
  Average (mean): 73.4 illustrations
  Median: 42 illustrations
  Total: 3,670 illustrations, 78% of the total.
• Q2: More illustrations: From nine to 22 illustrations.
  Average: 14.5 illustrations
  Median: 14 illustrations
  Total: 727 illustrations, 15.5% of the total.
• Q3: Average number of illustrations: From two to eight illustrations.
  Average: 4.7 illustrations.
  Median: 5 illustrations.
  Total: 246 illustrations, 5.2% of the total.
• Q4: Fewer illustrations: From zero to two illustrations.
  Average and Median: One illustration.
  Total: 48 illustrations, 1% of the total.

This one’s as close as you’re likely to get to a Pareto limit: 21.4% of the blogs had 80% of the illustrations.
