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.
Usage
1
2120
Format
A data frame with 60 observations on the following 5 variables.
- Student
a student identification number
- PriorExp
the student's prior expectation of rat-training
success, on a scale from -10 to 10
- Treatment
a factor with levels "bright" and "dull"
corresponding to whether students were told (falsely) that their rats were
bright or not
- Day
day of the study, ranging from 1 to 5
- Success
the number of successful maze runs on a day, out of 50
