1. Exercise 1.1.3<br />Reaction Time<br />The context:<br />You are driving on the high way and listening to the music you like most.<br />Suddenly, you see the brake light of the car in front of you just turned on.<br />You will try to hit the brake and slow down your car.<br />But, there is a small time delay before you really do that--- your reaction time.<br />[Reaction time: the lapse of time between stimulation and the beginning of response.]<br />The experiment:<br />Run the simulation for two different initial velocities. <br />V1= 60 Km/hr<br />V2 = 120 km/hr<br />Additionally, consider two frictional coefficients:<br />F1 = 0.8 (dry conditions)<br />F2 = 0.4 (rainy condition)<br />Repeat the experiment 10 times for each combination of conditions.<br />Data record was the Delay time and the Distance traveled.<br />Import the Excel data file to Statistica<br />File > Open > [Your Name] E1.1.2 Reaction Time.xls<br />Select: Import selected sheet in a spreadsheet.<br />Select: Get variables names from first row.<br />1.
