Reaction time with cell phone usage
Description
A simulated dataset on reaction time to an external event for subject using cell phones.
Usage
data(reaction.time)Format
A data frame with 60 observations on the following 4 variables.
- age
Age of participant coded as 16-24 or 25+
- gender
Male of Female
- control
Code to indicate if subject is using a cell phone "T" or is in the control group "C"
- time
Time in seconds to react to external event
Details
Several studies indicate that cell phone usage while driving can effect reaction times to external events. This dataset uses simulated data based on values from the NHTSA study "The Influence of the Use of Mobile Phones on Driver Situation Awareness".
