Correlation, Predication, Confidence, and Errors: Analysis of Statistics in the News

In statistics, there are a number of ways to compare how data is associated with the subject matters being discussed. In this paper, I will discuss how three different magazine articles use statistics to improve and expound on their theories, the methodology used, and if their use of statistics made the article more or less convincing. The statistical methods that will discuss statistics in the news include correlation, predication, confidence, and errors. Correlation “exists between two variables when higher values of one variable consistently go with higher values of another variable or when higher values of one variable consistently go with

The article states that mothers had a higher body mass index and ate a less healthy died with more sugary drinks and higher calorie and fat foods than women without children. (Rochman 2011) But the article also states that a corresponding BMI in fathers was unaffected, but didn’t give a theory for why that might have occurred.
The lead researcher who conducted the study, Jerica Berge, stated that the difference between mothers who ate more calories and childless women who ate fewer calories was “significant” (Rochman 2011), although when asked why it was significant, Berge wasn’t able, or willing, to establish the correlation or significance but didn’t disagree with the reporter when it was suggested that mothers might be eating the children’s leftovers which would be a potential causal relationship.
The text from Statistical Reasoning suggests that a correlation exists when higher values of one variable exist with higher values of another. However the article clearly states that although mothers and fathers were both parents to the children, the only one with significant negative outcomes were mothers without a corresponding outcome for fathers. And when pressed, the researcher
