Introduction

Anthropometric measurements are mainly concerned with assessing a person’s body composition in order to determine their nutrition status. In terms of composition, it assesses the density, fat, subcutaneous fat and the relative muscle mass. Such components provide valuable insights on an individual’s nutrition status, which is influenced by various factors including the quantity and quality of food intake, and a person’s physical health. As such, two extreme variations occur, ranging from malnutrition to obesity. In this context, anthropometric measurements provide tacit evidence of either under or over nutrition.

In this case, an assessment of the upper leg lengths of male and female participants is made which determines whether the legs are proportional in terms of growth. Proportional growth is essential as it influences the strength, locomotion and other physiological aspects. In order to obtain the data for the study, a survey design would be implemented in which systematic sampling would be used. In using systematic sampling, a sampling frame of N1 male subjects and N2 female subjects would first be chosen. Then N1 and N2 would be divided by the respective sample sizes for male and female subjects, n1 and n2. In doing this, two factors, K1 and K2 respectively, would be obtained and will represent the next subject to be selected into the sample for each gender until the samples n1 and n2 are obtained.

In taking measurements of upper leg length, a knee caliper and a steel measuring tape will be used. At first, the subject is instructed to sit with the knee positioned at a 900 angle. The knee caliper is then used to mark the starting point of measurement at the proximal border of the patel...

...m to the Chebychev rule and the empirical rule. In this context, the data values conform to the less stringent Chebychev rule but fail to satisfy the empirical rule. Essentially, the researcher can be 98% confident that the average upper leg length is between 37.47cm and 40.25cm for females, and between 41.50cm and 43.64cm for males. At the 90% level of confidence, the means would lie between 37.88cm and 39.85cm for females, and 41.71cm and 43.44cm for males.
