A recent health study sought to investigate whether taking baths was related to the incidence of cardiovascular disease. The analysis found there was a negative correlation between frequency of bath taking and the incidence of cardiovascular disease. Respond to the prompts below. Would it be appropriate to conclude from this that regular bath taking reduces the risk of cardiovascular disease? Explain why or why not. If you were to calculate a correlational coefficient for these two variables and it turned out to be -.45 how would you interpret this relationship? I.e., what is the strength of the relationship between the two variables? Calculate the coefficient of determination for the above correlation. What does this result tell you about the relationship between the variables? How might a third variable account for the apparent association between bath taking and cardiovascular disease? What additional research might you suggest to add additional clarity to the results reported above? Why?
