Chapter 4: Q 50. (page 253)

Effects of binge drinking A common definition of 鈥渂inge drinking鈥� is 5 or more drinks at one sitting for men and 4 or more for women. An observational study

finds that students who binge drink have lower average GPA than those who don鈥檛. Identify a lurking variable that may be confounded with the effects of binge drinking. Explain how confounding might occur.

Short Answer

Expert verified

Possible lurking variables are study habits, intelligence, income parents etc.

Step by step solution

01

Given information

We need to find a variable that could be confused with the consequences of binge drinking and figure out how that could happen.

02

Concept 

A lurking variable is one that is not included in the study's explanatory or response variables but has the potential to influence the response variable.

03

Explanation

One such hidden variable is the level of education enthusiasm. Alcohol consumption may result in lower marks for reasons other than academics. As a result, it's difficult to say if the kids' poor performance is related to the alcohol or simply an academic issue.

Wording bias Comment on each of the following as a potential sample survey question. Is the question clear? Is it slanted toward the desired response?

(a) 鈥淪ome cell phone users have developed brain cancer. Should all cell phones come with a warning label explaining the danger of using cell phones?鈥�

(b) 鈥淒o you agree that a national system of health insurance should be favored because it would provide health insurance for everyone and would reduce

administrative costs?鈥�

(c) 鈥淚n view of escalating environmental degradation and incipient resource depletion, would you favor economic incentives for recycling of resource-intensive consumer goods?鈥�

Treating prostate disease A large study used records from Canada鈥檚 national health care system to compare the effectiveness of two ways to treat prostate

disease. The two treatments are traditional surgery and a new method that does not require surgery. The records described many patients whose doctors had

chosen each method. The study found that patients treated by the new method were significantly more likely to die within eight years.

(a) Further study of the data showed that this conclusion was wrong. The extra deaths among patients who got the new method could be explained by lurking variables. What lurking variables might be confounded with a doctor鈥檚 choice of surgical or nonsurgical treatment?

(b) You have 300prostate patients who are willing to serve as subjects in an experiment to compare the two methods. Write a few sentences describing how you would design this experiment.

Testosterone for older menAs men age, their testosterone levels gradually decrease. This may cause a reduction in lean body mass, an increase in fat, and other undesirable changes. Do testosterone supplements reverse some of these effects? A study in the Netherlands assigned 237men aged 60-80with low or low-normal testosterone levels to either a testosterone supplement or a placebo. The report in the Journal of the American Medical Association described the study as a 鈥渄ouble-blind, randomized, placebo-controlled trial.鈥�40 Explain each of these

terms to someone who knows no statistics.

How was your stay? A hotel has 30 floors with 40 rooms per floor. The rooms on one side of the hotel face the water, while rooms on the other side face a

golf course. There is an extra charge for the rooms with a water view. The hotel manager wants to survey 120 guests who stayed at the hotel during a convention about their overall satisfaction with the property.

(a) Explain why choosing a stratified random sample might be preferable to an SRS in this case. What would you use as strata?

(b) Why might a cluster sample be a simpler option? What would you use as clusters?

Stronger players A football coach hears that a new exercise program will increase upper-body strength better than lifting weights. He is eager to test this new program in the off-season with the players on his high school team. The coach decides to let his players choose which of the two treatments they will undergo

for three weeks鈥攅xercise or weight lifting. He will use the number of push-ups a player can do at the end of the experiment as the response variable.

(a) Which principle of experimental design does the coach鈥檚 plan violate? Explain how this violation could lead to confounding.

(b) Comment on the coach鈥檚 choice of response variable.
