To research the claim that green tea lowers LDL (so-called bad) cholesterol, you ask a random sample of individuals to divulge w
hether they are regular green tea users or not. You also obtain their LDL cholesterol levels. Finally, you compare the LDL cholesterol levels of the green tea drinkers to those of the non-green tea drinkers. Explain why this is an observational study. A. This is an observational study because there is no intent to manipulate the explanatory variable, LDL cholesterol levels. B. This is an observational study because the researcher is manipulating the explanatory variable, whether the individual is a green tea drinker or not. C. This is an observational study because the researcher is manipulating the explanatory variable, LDL cholesterol levels. D. This is an observational study because there is no intent to manipulate the explanatory variable, whether the individual is a green tea drinker or not.
<u>It is an observational study</u><u> because the researcher is </u><u>NOT</u><u> manipulating the explanatory variable</u>, whether a person drinks green tea or not, in order to study the effect of the value it takes, over the dependent variable: LDL cholesterol level.
<u>In opposition, experimental studies manipulate the explanatory variable</u> in order to assess the effects caused on the dependent variable by such deviance.
Juliet’s sister is exhibiting the bias known as the out
group homogeneity. This is considered to be a tendency where in an individual
has a view in regards with the ingroup members that they consider it to be more
diverse than the members of the outgroup.
One of the primary observations made by the researchers after forty years of studying people that are consistently engaging in the anaerobic exercise was that these people are mostly likely much fitter and leaner. In addition, anaerobic exercise is a type of exercise wherein the body usually demands more oxygen that its capacity to hold.
