Statistics Blooper: Binge Drinking and Suicide Rates Line Graph
This is a major statistical blooper from the Wellness Clinic at University of Illinois. Firstly, the vertical axis does not have an appropriate variable for a line graph. It doesn't make sense to create a line graph among different states that are just alphabetically ordered. Secondly, the graph is not adjusted for different population sizes. It may seem like a state has low binge drinking and suicide rates compared to other states, but in actuality, the rates are very high in comparison to the total population (if the population size is small). Therefore, this graph doesn't give an accurate depiction of the binge drinking and suicide rates based on population size. Thirdly, it would be very helpful for there to be a key describing which color line refers to binge drinking or deaths. This would help the viewer better understand the graph.
