A multivariate study of three body measurements of different states of India.

Abstract

Considerable attempts have been made to study the changes in three important body measurements (viz. body height, body weight and chest circumference) in young healthy males between different states of India using univariate statistical analysis in which body measurements are assumed to be independent of each other. Actually these body measurements are correlated with each other and thus the assumption of independence is violated in univariate statistical analysis. Hence the results obtained by univariate statistical analysis may be misleading. An attempt has, therefore, been made in the present study to apply multivariate statistical analysis in order to have an idea about the simultaneous changes in these three correlated measurements between different states of India in healthy Indian males of age ranging from 16-21 years. It has been concluded that significant changes take place in these three body measurements simultaneously of young healthy males of 16-21 years of age between different states of India.
