Find an article, website, or blog that uses graphs to communicate
  1. Find an article, website, or blog that uses graphs to communicate information on a health-related topic. Select two different resources to discuss in your initial post: an effective graph and a poorly designed graph.
  2. Embed each graph in your initial post or provide the link with specific information on which graph is being evaluated. Be sure to reference your sources.

Introduction:
As a medical professor, it is important to teach students effective communication of data and information using various tools including graphs. In this post, I will discuss an effective graph and a poorly designed graph from two different resources that communicate information on a health-related topic.

1. The effective graph:
One of the effective graphs that I found is from the Centers for Disease Control and Prevention (CDC) website titled “Percent of High School Students Who Engaged in Physical Fights, by Race/Ethnicity and Sex, 2019” (https://www.cdc.gov/healthyyouth/data/yrbs/pdf/2019/ss6907_graph_pd.pdf). This graph effectively communicates the prevalence of physical fights among high school students based on race/ethnicity and gender. It is an effective graph because it uses simple and clear visuals with specific colors and clear labeling of axes and categories, making it easy to interpret the data. The graph also has a clear title that describes the variables being measured.

2. The poorly designed graph:
The poorly designed graph that I found is from a blog titled “The Worst Nutrition Studies Ever Conducted” (https://healthinsightuk.org/2020/04/30/the-worst-nutrition-studies-ever-conducted/). The graph attempts to show the relationship between dietary cholesterol intake and serum cholesterol levels. However, the graph is poorly designed because it uses a 3D perspective that distorts the data and makes it difficult to compare the values on the Y-axis. The labeling on the X-axis is also unclear, with no unit of measurement provided. Moreover, the title does not provide a clear description of the variables being measured.

In conclusion, effective graph design is crucial to communicate health-related data and information accurately and efficiently. Medical students must learn to evaluate and create effective graphs to become proficient healthcare practitioners.
