12.26? Does haptic feedback improveperformance?
A group of technology students is interested in whether hapticfeedback (forces and vibrations applied through a joystick) ishelpful in navigating a simulated game environment they created. Toinvestigate this, they randomly assign 20 students to each of threejoystick controller types and record the time (seconds) it takes tocomplete a navigation mission. The joystick types are (1) astandard video game joystick, (2) a game joystick with forcefeedback, and (3) a game joystick with vibration feedback. Usingthe table below of group means and standard deviations, constructan ANOVA table. Based on the F statisticand degrees of freedom, compute the P-value. What do youconclude?
