Assuming, as these results indicate, that activities in
coarse and fine mestes do not differ, the ratto of coarse to
fine should be unity. The ratios in Table 9 were used to
determine variability on the vet a9 crresed ts ths a3h besis.
On the ash besis, variance vas only half as great as on the
vet basis, thus, eshn is considered the better basis.
Conversion to logarithms was necessary to normalize the skeved
(with peak toward the left) frequency distribution of the two
arrays of ratices.
