Association Between Diet Quality and CVD Events in a Large Population

Inferential Statistics: Identifying Hypothesis
A hypothesis predicts connections between variables being tested in a study. In some cases, the hypothesis can go as far as state the correlation, but most hypothesis just guesses whether there is a connection between variables or not.             In the study by Dehghan et al. (2012), identifying the hypothesis can be tricky because it does not use “if…then” statements. Moreover, utilize the form of null/alternative hypothesis which states the kind of relationship that may be discovered from the data available. But just like most hypothesis, Dehghan et al. states the hypothesis right in the introduction: “Epidemiological studies have shown a lower risk of CVD events associated with healthy diets in those without prior CVD” (Dehghan et al., 2012). The researchers went on to discuss various research design utilized by epidemiological studies (prospective studies, randomized trials, observational cohort studies), and then settles on one research design to test the “relationship of dietary patterns in high-risk individua...
