Anonymous? Confidential? One of the most important non-government surveys in the United States is the National Opinion Research Center鈥檚 General Social Survey. The GSS regularly monitors public opinion on a wide variety of political and social issues. Interviews are conducted in person in the subject鈥檚 home. Are a subject鈥檚 responses to GSS questions anonymous, confidential, or both? Explain your answer.

Short Answer

Expert verified

It is confidential.

Step by step solution

01

Given information

The GSS tracks public opinion on a wide range of political and social issues on a regular basis.

02

Concept

Individuals are purposely subjected to a treatment in order to measure their responses in an experiment.

03

Explanation

The GSS surveys public opinion on a variety of political and social issues on a regular basis, as stated in the question. In-person interviews were performed at the subject's residence. Because the interviews are performed in person at the subject's home, the subject's responses to GSS questions are not anonymous, but they are confidential because the interviewer will not discuss the results of a specific individual.

Layoffs and 鈥渟urvivor guilt鈥 Workers who survive a layoff of other employees at their location may suffer from 鈥渟urvivor guilt.鈥 A study of survivor guilt and its effects used as subjects120students who were offered an opportunity to earn extra course credit by doing proofreading. Each subject worked in the same

cubicle as another student, who was an accomplice of the experimenters. At a break midway through the work, one of three things happened:

Treatment 1: The accomplice was told to leave; it was explained that this was because she performed poorly.

Treatment 2: It was explained that unforeseen circumstances meant there was only enough work for one person. By 鈥渃hance,鈥 the accomplice was chosen to

be laid off.

Treatment 3: Both students continued to work after the break.

The subjects鈥 work performance after the break was compared with performance before the break. Describe how you would randomly assign the

subjects to the treatments

(a) using slips of paper.

(b) using Table D.

(c) using technology.

The manager of a sports arena wants to learn more about the financial status of the people who are attending an NBA basketball game. He would like to give a survey to a representative sample of the more than 20,000 fans in attendance. Ticket prices for the game vary a great deal: seats near the court cost over \(100 each, while seats in the top rows of the arena cost \)25 each. The arena is divided into 30 numbered sections, from 101 to 130 Each section has rows of seats labeled with letters from A (nearest the court) to ZZ (top row

of the arena).

Systematic random sample Sample surveys often use a systematic random sample to choose a sample of apartments in a large building or housing units in a block at the last stage of a multistage sample. Here is a description of how to choose a systematic random sample. Suppose that we must choose 4 addresses out of 100 Because 100/4=25 we can think of the list as four lists of 25 addresses. Choose 1 of the first 25 addresses at random using Table D. The sample contains this address and the addresses 25,50, and 75 places down the list from it. If the table gives 13, for example, then the systematic random sample consists of the addresses numbered 13,38,63, and 88

(a) Use Table D to choose a systematic random sample of 5 addresses from a list of 200 Enter the table at line 120

(b) Like an SRS, a systematic random sample gives all individuals the same chance to be chosen. Explain why this is true. Then explain carefully why a systematic sample is not an SRS.

Does reducing screen brightness increase battery life in laptop computers? To find out, researchers obtained 30new laptops of the same brand. They chose 15of the computers at random and adjusted their screens to the brightest setting. The other 15laptop screens were left at the default setting鈥攎oderate brightness. Researchers then measured how long each machine鈥檚 battery lasted.

More rain for California? The changing climate will probably bring more rain to California, but we don鈥檛 know whether the additional rain will come during the

winter wet season or extend into the long dry season in spring and summer. Kenwyn Suttle of the University of California at Berkeley and his coworkers carried

out an experiment to study the effects of more rain in either season. They randomly assigned plots of open grassland to three treatments: added water equal to 20%of annual rainfall either during January to March (winter) or during April to June (spring), and no added water (control). Thirty-six circular plots of area 70square meters were available (see the photo), of which 18were used for this study. One response variable was total plant biomass, in grams per square meter, produced in a plot over a year.

(a) Outline the design of the experiment. What is this type of design called?

(b) Explain how you would randomly assign the experimental units to the three treatments. Then carry out your random assignment.
