Purple Staining of Archaeological Human Bone: An Investigation of Probable Cause and Implications for Other Tissues and Artifacts
Table 1
Calculated prevalence values for the presence of colored bone classified according to broad age groups, biological sex where observable, and combined as a whole. The lower and upper levels of the respective 95% confidence intervals for the prevalence values are included to test the null hypothesis that there is no variation of prevalence across the various categories. The 95% confidence intervals for all the subgroups overlap indicating that the null hypothesis holds at the 5% significance level (: number of individuals; CI: confidence interval).
