Chapter 4: Q. 4.10 (page 289)

Students sign up to be subjects in a psychology experiment. When they arrive, they are told that interviews are running late and are taken to a waiting room. The experimenters then stage the theft of a valuable object left in the waiting room. Some subjects are alone with the thief, and others are present in pairs—these are the treatments being compared. Will the subject report the theft?

a. The students had agreed to take part in an unspecified study, and the true nature of the experiment is explained to them afterward. Does this meet the requirement of informed consent? Explain your answer.

b. What two other ethical principles should be followed in this study?

Short Answer

Expert verified

a. No, this doesn't meet the requirement of informed consent.

b. The two other ethical principles that should be followed in the study are confidentiality and review board.

Step by step solution

01

Part (a) step 1: Given Information

We need to explain does this meet the requirement of informed consent.

02

Part (a) step 2: Explanation

No, because informed consent means that subjects are informed before the experiment and in this experiment, they are informed afterward.

03

Part (b) step 1: Given Information

We need to find two other ethical principles that should be followed in the study.

04

Part (b) step 2: Explanation

Confidentiality is needed for each individual.

A review board should have reviewed the experiment before it will be implemented.

A recent random sample of n=805adult U.S. residents found that the proportion who rated the honesty and ethical standards of nurses as high or very high is 0.85. This is 0.15higher than the proportion recorded for doctors, the next highest-ranked profession.

a. Identify the sample and the population in this setting.

b. Do you think that the proportion of all U.S. residents who would rate the honesty and ethical standards of nurses as high or very high is exactly 0.85? Explain your answer.

c. What is the benefit of increasing the sample size in this context?

Want a snack- Can snacking on fruit rather than candy reduce later food consumption? Researchers randomly assigned12women to eat either65 calories of berries or 65calories of candy. Two hours later, all 12women were given an unlimited amount of pasta to eat. The researchers recorded the amount of pasta consumed by each subject. The women who ate the berries consumed133 fewer calories, on average. Identify the

explanatory and response variables, the experimental units, and the treatments.

Online polls Parade magazine posed the following question: “Should drivers be banned

from using all cell phones?” Readers were encouraged to vote online at parade.com. The

subsequent issue of Parade reported the results:2407(85%)said “Yes” and 410(15%)

said “No.”

a. What type of sample did the Parade survey obtain?

b. Explain why this sampling method is biased. Is 85%probably greater than or less than

the true percent of all adults who believe that all cell phone use while driving should be

banned? Why?

You wonder if TV ads are more effective when they are longer or repeated more often

or both. So you design an experiment. You prepare 30-second and 60-second ads for a

camera. Your subjects all watch the same TV program, but you assign them at random

to four groups. One group sees the 30-second ad once during the program; another sees

it three times; the third group sees the 60-second ad once; and the last group sees the

60-second ad three times. You ask all subjects how likely they are to buy the camera.

Which of the following best describes the design of this experiment?

a. This is a randomized block design, but not a matched pairs design.

b. This is a matched pairs design.

c. This is a completely randomized design with one explanatory variable (factor).

d. This is a completely randomized design with two explanatory variables (factors).

e. This is a completely randomized design with four explanatory variables (factors).

A local news agency conducted a survey about unemployment by randomly dialing phone

numbers during the work day until it gathered responses from 1000 adults in its state. In

the survey, 19% of those who responded said they were not currently employed. In reality,

only 6% of the adults in the state were not currently employed at the time of the survey.

Which of the following best explains the difference in the two percentages?

a. The difference is due to sampling variability. We shouldn’t expect the results of a

random sample to match the truth about the population every time.

b. The difference is due to response bias. Adults who are employed are likely to lie and

say that they are unemployed.

c. The difference is due to undercoverage bias. The survey included only adults and did

not include teenagers who are eligible to work.

d. The difference is due to nonresponse bias. Adults who are employed are less likely to

be available for the sample than adults who are unemployed.

e. The difference is due to voluntary response. Adults are able to volunteer as a member

of the sample.
