This is an observational study because the researcher manipulating the explanatory variable, whether the individual is a green tea drinker or not. O c. This is an observational study because the researcher 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 not. (b) Name some lurking variables that might exist in the study. Select all that apply. A. Age OB. Diet C. Number of siblings OD. Exercise E. Genetics Gender

Answer 1

Lurking variables: Lurking variables is the variable that is not included as an explanatory or response variable in the analysis but can affect the interpretation of relationship between variables. Among the given options choose the Lurking variable. The given Lurking variables are: • Age Diet Number of siblings Exercise Genetics Gender Here Age, diet, exercise, genetics, gender are the Lurking variables. Because, these variables are not included as the response variables in the analysis but can affect the interpretation. Hence theses are treated as the Lurking variables. Therefore, "Age, Diet, Exercise, Genetics, Gender" are the Lurking variables.
