Analysis of Hand Grip Strength and BMI in Grandparent Carers

This assignment delves into the statistical analysis of hand grip strength and Body Mass Index (BMI) data collected from a sample of grandparent carers. The analysis begins by classifying hand grip strength as a continuous variable and then proceeds to examine the distribution of BMI categories and the characteristics of BMI distribution using measures of center, spread, and shape. The study further investigates the relationship between hand grip strength and BMI, as well as the relationship between hand grip strength and WHO body mass classification. The assignment also explores the association between occupational history and BMI categories using contingency tables and Chi-square tests. Furthermore, it applies binomial distribution to analyze the probability of obesity and uses the Central Limit Theorem to determine the mean and standard deviation of hand grip strength. Finally, the document calculates Z-scores to find probabilities related to hand grip strength and uses these results to make inferences about the health of the grandparent carers. The study is supported by R-output to justify the statistical findings.
