## Evaluate the effect of the intervention on body mass index in the intervention compared to the control group.

Assessment question for Applied Statistics and Data Analysis for Public Health (MMB725024)

The healthy lifestyle dataset provided is obtained from a hypothetical study which was conducted to evaluate a lifestyle health education intervention. The aim of the intervention was to promote healthy lifestyles among university students. Improving health literacy and reducing weight were some of the objectives of the study. Details of variables in the dataset are presented in table 1 below.

Using the information provided, conduct statistical analysis to address the following objectives and present your findings in a 3000-word statistical analysis report.

1. Evaluate the effect of the intervention on body mass index in:
1. the intervention group
2. the control group
2. Evaluate the effect of the intervention on body mass index in the intervention compared to the control group.
3. Examine whether there is statistically significant difference in the proportion of diabetes cases between the intervention and control groups.
4. Determine whether there is statistically significant difference in health literacy between the intervention and control groups.
5. Investigate and explain how health literacy, age and sex can be used to predict post-intervention body mass index among participants in the study.
