There are several different means of grouping the data collected from the current<br />
study in order to perform statistical analyses. The first approach was to group all the data<br />
for both genders and compare by the region from which the specimens were removed. This<br />
revealed that the average peak strain in all the anterior specimens was significantly lower<br />
than both the lateral (P=0.01) and posterior (P=0.01) specimens. The average peak stress<br />
values showed the same relationship in that they were significantly lower for the anterior<br />
specimens when compared to lateral (P=0.01) and posterior (P=0.01) specimens. The<br />
moment of inertia of the anterior specimens was lower than the lateral specimens, on the<br />
average (P=0.07), however, the difference was not statistically significant. The average<br />
moment of inertia of the lateral specimens was lower than the average posterior values for<br />
all specimens (P=0.06), but again, the difference was not statistically significant.<br />
Grouping all data from all regions between the two genders resulted in only one<br />
significant difference. The difference in the moment of inertia of all male and female rib<br />
specimens was the only variable found to be statistically significant (P=0.01) at this level of<br />
grouping. Female moment of inertia values were significantly lower than that of the male<br />
subjects. The peak stress for all the female specimens, was lower on the average when<br />
compared to the male specimens, but fell short of being statistically significant (P=0.07).<br />
Dividing the rib specimen data between genders revealed more significant<br />
differences in the anterior, lateral and posterior regions among the two genders. These<br />
comparisons were performed by focusing on one location and comparing between the two<br />
genders. Among the anterior specimens, the average peak strain for the female subjects<br />
was significantly lower than the male anterior specimens (P=0.01). The average moment<br />
of inertia of the female specimens was significantly lower at all three locations, the anterior<br />
