I. Objective
* To demonstrate the functional relationship between work load and heart rate.
* To be acquainted with the techniques for measurement of work load and heart rate.
II. Working Hypothesis
* Heart Rate (beat/min)= work (kj/min)
III. Procedures
* At rest (for every member of the class.)
Rest for 5 minutes, measure BPM.
* Walking
Walk across the classroom (poor to window back and forth)
* Climbing stairs
Climb 4th floor up to classroom. Measure BPM.

IV. Data
V. Data Analysis
1. Plot the data for heart rate: work
2. Compute for coefficient of correlation.
3. Compute the compute-using linear regression.
1. Data for Heart Rate: Work
2. Coefficient of Correlation
[pic]Formula:
r= (13)(67,741)-(888)(980)
√{(13)(61,594)-(788,544)}{(13)(74,784)-(960,400)}
r= 0.867
b= 10,393/12,778
b=0.81
a=75.38-0.81(68.31)
a=20.05
