Table 7. Fourteen Radiocarbon Dates <strong>and</strong> Calibrated Date Ranges for Green Castle <strong>and</strong> Related<br />

Sites.<br />

It is instructive to compare these dates with those obtained for sites in the<br />

Annotto Bay area as part of the UWI–Murray State University project mentioned<br />

in Chapter 2 ( Allsworth- Jones <strong>and</strong> Wesler 2003). This project encompasses<br />

Green Castle (Y25), Newry (Y27), Coleraine (Y19), <strong>and</strong> Wentworth<br />

(Y8), which is somewhat farther to the west. The results are set out in Table 7,<br />

which has been drawn up in the same manner as discussed above. There are 14<br />

calibrated dates all told, eight of them being from Green Castle. One of the<br />

Green Castle results (Beta-134378) <strong>and</strong> three of those from Coleraine (Beta-<br />

182409–11) have been excluded as evidently contaminated. Broadly speaking,<br />

the results are similar, but the information from the two sets of data as a<br />

whole can be explicitly compared making use of the median dates already mentioned.<br />

The method chosen has been to employ age dispersion diagrams along the<br />

lines of those originally proposed by Ottaway (1973) except that now calibrated<br />

medians rather than radiocarbon dates are used. In this method, the<br />

range, the median, <strong>and</strong> the interquartile range of the dates under consideration
