Article Analysis: Breast Cancer and Survival Disparities

This assignment analyzes two research articles related to breast cancer. The first article examines the risk of breast cancer among women under 55 concerning oral contraceptive use and hormone replacement therapy, while the second investigates factors contributing to black-white disparities in survival among nonelderly women with breast cancer. The analysis includes identifying independent and dependent variables, the population of interest, sample sizes, and sampling methods. It also highlights examples of descriptive and inferential statistics used in each study, such as relative risks and survival rates. The assignment provides a structured breakdown of the articles, allowing for a comprehensive understanding of the research methodologies and findings. This analysis covers the key elements of the research articles, offering insights into the study designs, populations, and statistical analyses. The assignment aims to provide a thorough understanding of the research articles and their findings.
