Indian Craniometric Variability and Affinities

Table 4

Relationship between measurements’ mean and range for Indian series.

Linear measurements included	Untransformed variables		Variables transformed to base 10 logarithms
	Pearson’s 𝑟	Slope of best fit line	Pearson’s 𝑟	Slope of best fit line
All measurements, all series	0.699	0.142	0.752	0.438
All measurements except fractions, all series	0.752	0.146	0.767	0.433
All measurements except fractions, all series with ≥30 values per measurement	0.852	0.166	0.878^a	0.420^b

aPearson’s 𝑟 value is 0.883 for northern Indians and 0.876 for southern Indians.
^bSlope of best fit line is 0.431 for northern Indians and 0.411 for southern Indians.
