Statistical analysis using a 2 tailed t-test of the angular dependence of the modulus of skin (Figure 4). The 0° angle defined as the angle where the maximum modulus is measured. Only the moduli at 0° and 67.5° at 5% strain are significantly different than that of the unstretched skin.
| Condition | Average Modulus Value | Standard Deviation | Sample Size | p Value | Significance |
|---|---|---|---|---|---|
| Control (No strain) | 2.34 × 106 | 6.91 × 105 | 17 | NA | NA |

Strain Direction: 0 degree
(5 Percent Strain) |
3.55 × 106 | 2.56 × 105 | 5 | 1.88 × 10−4 * | Significant |
|
Strain direction: 67.5 degree
(5 Percent Strain) |
3.03 × 106 | 4.07 × 105 | 6 | 1.31 × 10−2 * | Significant |

Strain direction along 22.5, 45, 90, −67.5, −45, −22.5 degrees
(5 Percent strain) |
2.54 × 106 | 3.12 × 105 | 27 | 1.56 × 10−1 | Not Significant |
