Hypothesis: When obesity and poverty rates are tested to see which is more correlated with life expectancy I would expect poverty to be more correlated and for it to be a negative correlation as well. I say this because obesity is in a way a subcategory of poverty. For example, people who are poorer tend to buy the less healthy foods because they are at a cheaper price, thusly causing obesity.
Procedure:
Research and Identify the obesity rate and poverty rate for 30 countries.
(The World Factbook)
Develop a spreadsheet of all countries’ data.
Use data from spreadsheet to construct two separate scatter plot graphs comparing Life Expectancy to the two other variables, Obesity Rate …show more content…
Upon further analysis, I discovered that the prediction was in some ways correct and supported by the data, but in other ways deviated slightly. What was found to be correctly assumed is that poverty rates tend to be negatively correlated with life expectancy. On the other hand, it was discovered that both obesity and poverty rates seems to be closely correlated with life expectancy. They were both about five hundredths from each other in value, but the difference being one was positively correlated and the other …show more content…
The reason for it being an outlier of the data was becuase it had a high life expectancy (80yrs.), but a low obesity rate (6.3%). In South Korea the country's economy along with its diet changed greatly in the 1970’s. Some changes included: a change in consumption of animal food products, a lessening of fat consumption, as well as a decline in cereal and other grain consumptions (American Journal Clinical Nutrition). An additional outlier that was for life expectancy and poverty was Greece. The reason it is an outlier is due to the fact that it has a high life expectancy (80.4yrs.) and a high poverty rate (44%). In Greece, “the country has already endured years of economic contraction.” Starting in around 2008, the economy has been getting worse and worse with only a slight incline. “The recession has cut the size of the Greek economy by around a quarter.” This meant it was largest contraction of an advanced economy since the 1950s.” (Lucy Rodgers, Nassos
