ex2120: Clever Hans Effect
Description
These data were simulated to match the summary statistics and conclusions of
Rosenthal and Fode's Clever Hans experiment. Each of 12 students trained rats
to run a maze. The data set contains their number of successful runs
out of 50 on each of 5 days, the student's prior expectation of success (on a
scale from -10 to 10), and a variable indicating treatment--whether or not the
students were supplied with the fictitious information that their rights were
bright.source
