Anagram puzzles involve sets of scrambled letters that must be rearranged
to form words. A standard intelligence test employs these puzzles as an aid
in assessing verbal ability. Several years ago, an undergraduate noticed
that some versions of the intelligence test employed anagram puzzles with
lower-case letters, and some versions employed anagram puzzles with
upper-case letters. She performed experiments, with college students as
participants, to examine the completion times for the two versions. The
histogram below is the figure that summarizes her information for the
completion times of the 25 students being tested on the lower-case version.
