A data frame with 38 rows and 2 variables:
Independent variable: group one or group two
Dependent variable: Contact time in seconds
The data come from a study by Dana (1990, cited in Wilcox 2009) in which individuals tried to keep an apparatus in contact with a target. There was one experimental condition with two levels (group one and group two). The dependent variable is the number of seconds participants could keep in contact with the target.
