WEIGHT LOSS GRAPH
The graph above shows the average weight loss results from a medical weight loss procedure. A woman comes across this graph on the internet and tells her friend who weights 375 lbs and plans on receiving the medical weight loss treatment hat she should try to reach 400 lbs. She explains to her friend that according to the graph, the higher your starting weight, the more weight patients lose. Do you agree with her analysis? What are some of the risks of incorrectly analyzing a graph?
