Chapter 4: Q 36. (page 229)

Checking for 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) Which of the following best represents your opinion on gun control?

1. The government should confiscate our guns.

2. We have the right to keep and bear arms.

(b) A freeze on nuclear weapons should be favored because it would begin a much-needed process to stop everyone in the world from building nuclear

weapons now and reduce the possibility of nuclear war in the future. Do you agree or disagree?

Part (a) Wording: Clear

Slanted: No

Part (b) Wording: Unclear

Slanted: No

Step by step solution

01

 Part (a) Step 1: Given information

Consider each of the following as a possible survey question sample. Is the question straightforward? Is it skewed toward a particular response?

02

Part (a) Step 2: Concept

A sample survey picks a group of people from a larger group of people about whom we want to learn more. The data from the sample is used to draw inferences about the population. It's critical to be specific about the demographic you're interested in and the characteristics you'll track.

03

Part (a) Step 3: Explanation

We need to change the phrasing and make it slanted.

The question is whether the government should seize guns or not.

Slanted: No, because it has no bearing on which of the two options is chosen (gun control).

04

Part (b) Step 1: Explanation

We need to change the phrasing and make it slanted.

Wording: Uncertain because the statement is quite long and difficult for others to understand. As a result, we can create a distinct, shorter statement to better understand the question.

Slanted: Yes, because the comment of minimizing the probability of uncertain war can encourage individuals to answer "Agree."

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.

Doctors and nurses Nurse-practitioners are nurses with advanced qualifications who often act much like primary-care physicians. Are they as effective as doctors at treating patients with chronic conditions? An experiment was conducted with 1316patients who had been diagnosed with asthma, diabetes, or high blood pressure. Within each condition, patients were randomly assigned to either a doctor or a nurse-practitioner. The response variables included measures of the patients鈥� health and of their satisfaction with their medical care after six months.

(a) Which are the blocks in this experiment: the different diagnoses (asthma, etc.) or the type of care (nurse or doctor)? Why?

(b) Explain why a randomized block design is preferable to a completely randomized design in this setting.

A survey paid for by makers of disposable diapers found that 84% of the sample opposed banning disposable diapers. Here is the actual question:

It is estimated that disposable diapers account for less than 2%of the trash in today鈥檚 landfills. In contrast, beverage containers, third-class mail, and yard wastes are estimated to account for about 21% of the trash in landfills. Given this, in your opinion, would it be fair to ban disposable diapers? Explain how the wording of the question could result in bias. Be sure to specify the direction of the bias.
