(S. Idell Pyle, et al., Onsets, Completions, and...)

In contrast , 20 of the 21 lines in the Completion Profile ( excluding center 5 for boys and 4 for girls ) are bunched and extend over a much shorter period , approximately 30 months for boys and 40 months for girls .

Second , for both sexes , the 21 transverse lines in the Onset Profile vary more in individual spread than those in the Completion Profile .

It was stated earlier that one purpose of this study was to extend the analysis of variability of Onset and Completion in each of the 21 growth centers somewhat beyond that provided by the data in Tables 1 and 2 .

The numbering system used in Tables 1 and 2 and Figures 1 and 2 was continued for the 21 growth centers .

Thus , the alignment of the `` dots '' and `` tips '' , respectively , indicate individual variability of the 21 growth centers of each child with_respect_to the mean values for these boys and girls .
