Fingers
Format
A dataset with 12 observations on the following 3 variables.
Subject I, II, III, or IV
Drug Caffeine, Placebo, or Theobromine
TapRate Finger taps in a fixed time interval
Details
Scientists Scott and Chen, published
research that compared the effects of caffeine with those of theobromine (a similar chemical
found in chocolate) and with those of a placebo. Their experiment used four human subjects, and
took place over several days. Each day each subject swallowed a tablet containing one of caffeine,
theobromine, or the placebo. Two hours later they were timed while tapping a finger in a specified
manner (that they had practiced earlier, to control for learning effects). The response is the number
of taps in a fixed time interval

The data was found in Statistics in Biology, Vol. 1, by C. I. Bliss (1967), New York: McGraw Hill.
