Statistical Analysis of Second-Hand Smoke Exposure: A Comprehensive Study

Second-hand smoke, commonly referred to as passive smoking, is the involuntary inhalation of

tobacco smoke from the surrounding environment. It contains many harmful substances known to

have adverse effects on human health. Despite public health efforts aimed at reducing smoking,

exposure to second-hand smoke remains prevalent, mainly at home and in social settings.

This project examines the relationship between second-hand smoke exposure and various health

and behavioral outcomes, including headache frequency, respiratory symptoms, smoking initiation,

physical activity, and stress levels. Using a dataset of 100 individuals, the study applies descriptive

statistics, inferential hypothesis testing, and regression analysis to evaluate these relationships.

The aim of this analysis is to quantify the impact of second-hand smoke exposure using appropriate

statistical methods and visualizations, and to highlight its potential health implications.
