Industrial Statistics with Minitab

2.1 File ‘PULSE’

An experiment is conducted in a class with 92 students, where initially each student registers his or her own height, weight, gender, smoking preference, usual physical activity level and resting pulse rate. Then, each student flips a coin and those who get a face coming up must run in place for one minute. Finally, after that time, all measure and register their new pulse rates.

The file named PULSE.MTW, included in the Minitab sample data folder, will be used throughout this chapter to illustrate the different type of graphs that can be constructed. This file is organized as follows:

Column	Variable	Label
C1	Pulse1	First pulse rate of the 92 students
C2	Pulse2	Second pulse rate
C3	Ran	1=ran in place; 2=did not run in place
C4	Smokes	1=smokes regularly; 2=does not smoke regularly
C5	Sex	1=male; 2=female
C6	Height	Height (in inches)
C7	Weight	Weight (in pounds)
C8	Activity	Usual level of physical activity: 1=slight; 2=moderate; 3=a lot
