Control Chart and Its Applicationin Modelling Body Mass Index (BMI) of Students in Delta State Polytechnic, Oghara

Abstract

This study aimed to examine the health status of students as a function of the body mass index (BMI) using control chart. The utility of body mass index has proven very useful in helping managers to estimate the weight normality of individuals as a measure of healthy living among them. This study evaluated the reported BMI of students and problems associated with abnormal BMI among students. Stratified sampling was adopted since there are three faculties or schools in the polytechnic with each school having several departments, therefore, A simple random sample of 150 students was selected from the three schools of study in the Delta State Polytechnic, Otefe-Oghara and their BMI were examined through data on weight and height. The result of the study revealed that the students BMI are statistically in control for X-chat and out of control for MR-chat in engineering, both X-chart and MR-chart are out of control for Applied sciences but for school of business, both chats are in statistical control. The fact that the test for randomness proved to be false; it implies that the sample result is evident enough to infer on the general population that their current measures of body mass index are not random. Consequent to the study findings, it was concluded that quality control tools: (control chart for individual unit) is a veritable too for student BMI diagnostics. The study also concludes that most students’ BMI was classified according to the World Health Organization (WHO) standard to be obese, which indicates a huge health risk of various obese-related diseases like diabetes, cardiac issues and even stroke especially for school of engineering and applied sciences.
