The equation of band resistance and R2 values.
| Band Color | Regression Equation | R2 |
|---|---|---|
| Purple | y = 20.802 ln(x) − 90.809 | 0.945 |
| Red | y = 39.03 ln(x) − 171.9 | 0.983 |
| Blue | y = 51.831 ln(x) − 227.85 | 0.989 |
| Green | y = 90.823 ln(x) − 395.29 | 0.991 |
x = linear band deformation (cm); y = resistance applied (kg); and ln = natural log.
