Final answer:
A. Shows a clear difference in maxhr distribution between diagnosed and not diagnosed patients.
Explanation:
The side-by-side boxplot of maxhr for patients diagnosed and not diagnosed with heart disease distinctly exhibits a noticeable contrast in their distributions. The visual representation highlights a clear separation between the two groups, indicating significant differences in maximum heart rates (maxhr) between those diagnosed and not diagnosed with heart disease. The boxplot portrays higher maxhr values for diagnosed patients compared to those without the diagnosis, implying a clear distinction in their maxhr distributions.
The boxplot's interpretation reveals that patients diagnosed with heart disease tend to have higher maximum heart rates, suggesting a possible correlation between elevated maxhr and the presence of heart disease. This graphical representation aids in visualizing the disparity, serving as a valuable tool for clinicians and researchers to discern patterns and differences in maxhr distribution among patients with and without a heart disease diagnosis.
In summary, the side-by-side boxplot effectively demonstrates a distinct discrepancy in maxhr distribution between diagnosed and not diagnosed patients, emphasizing the potential association between higher maxhr and the presence of heart disease.
