Discover the critical importance of accurate data visualization in COVID-19 health policy decisions with Dr. Heather Mattie, a biostatistics lecturer and co-director of the Health Data Science Master's program at Harvard T.H. Chan School of Public Health. This video examines a misleading bar graph used by the Georgia Department of Public Health in May 2020 to justify reopening the state. Dr. Mattie highlights the errors in the graph, including the non-chronological x-axis and inconsistent bar order, and presents a corrected version to reveal the true trends in COVID-19 cases. Learn how accurate data visualization is essential for transparent scientific communication and effective health policy.
