Relationship between indices’ mean and variability (other than nasal flatness indices) for Indian series.

Series included and measure of variability compared	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 series (standard deviations)	0.644	0.028	0.684	0.369
All series with ≥30 values per index (standard deviations)	0.740	0.028	0.781^a	0.367^b
All series (ranges)	0.509	0.116	0.493	0.351
All series with ≥30 values per index (ranges)	0.637	0.126	0.684^c	0.327^d

aPearson’s 𝑟 value is 0.797 for northern Indians and 0.768 for southern Indians.
^bSlope of best fit line is 0.371 for northern Indians and 0.364 for southern Indians.
^cPearson’s 𝑟 value is 0.725 for northern Indians and 0.660 for southern Indians.
^dSlope of best fit line is 0.345 for northern Indians and 0.316 for southern Indians.
