1 SOME QUESTIONS???? PAPIA BAWA Class Exercise

2 Question Set 1 Suppose we are trying to gather statistics regarding the efficacy of the death penalty. Here are some ways to design the questions:

3 Option a Do you support the death penalty? Yes No

4 Option b Which one do you consider to be a better option: The death penalty Life in prison without the possibility of parole

5 Option c Which of these do you consider to be the best alternative: The death penalty Life in prison without the possibility of parole Life in prison without the possibility of parole with the inmates working in prison to pay restitution to their victims’ families.

6 Let us see the results… Yes" or "No" have found 70-75% of the respondents choosing ”Yes” in favor of death penalty. The choice between the death penalty and life in prison without the possibility of parole show support for the death penalty at about 50-60%. The alternatives of the death penalty or life in prison without the possibility of parole, with the inmates working in prison to pay restitution to their victims’ families have found support for the death penalty closer to 30%. !!!!

7 So what is the true level of support for the death penalty? The lowest figure is probably truest, since it represents the percentage that favor that option regardless of the alternative offered. The need to include all relevant alternatives is not limited to political polls. You can get misleading data anytime you leave out alternatives.

8 Question Set 2 "Do you buy frozen meat and frozen fish?" Yes No

9 OR "Have you ever bought Product X and, if so, did you like it?" Yes No

10 How could this pan out…. "Do you buy frozen meat and frozen fish?" A "Yes" answer can mean the respondent buys meat or fish or both. "Have you ever bought Product X and, if so, did you like it?" A "No" answer can mean "never bought" or "bought and disliked."

11 Question Set 3: Option a "Do you ever buy pasta?" Yes No

12 Option b "Have you bought pasta (other than in a restaurant) in the last three months?“ "If yes, was it frozen, canned or dried?"

13 Which option is better? Option b, of course! It is more specific and is based on realistic expectations. Few people can remember what they bought more than three months ago unless it was a major purchase such as an automobile or appliance.

14 Question Set 4: Option a "Do you use regular or premium gas in your car?"

15 Option b "Which type(s) of fuel do you use in your cars?" Regular gasoline Premium gasoline Diesel Other Do not have a car

16 Which is the better one? Option b Option a does not cover all possible answers. The owner may alternate between both types.

17 Question Set 5 In which of the following do you live? A house An apartment The suburbs

18 The question is faulty… In which of the following do you live? A house An apartment The suburbs The options are not mutually exclusive. This question ignores the possibility of someone living in a house or an apartment in the suburbs

19 Question 6 What do you think about product X? It's the best on the market It's about average It's the worst on the market

20 The question is faulty… What do you think about product X? It's the best on the market It's about average It's the worst on the market The rating scale labels are not meaningful A question phrased like the one above will force most answers into the middle category, resulting in very little usable information.

21 Question 7 Asking a question that does not accommodate all possible responses can confuse and frustrate the respondent. For example, consider the question: What brand of computer do you own? __ A. IBM PC B. Apple

22 Clearly, there are many problems with this question What if the respondent doesn't own a microcomputer? What if he owns a different brand of computer? What if he owns both an IBM PC and an Apple?

23 There are two ways to correct this kind of problem. The first way is to make each response a separate dichotomous item on the questionnaire. For example: Do you own an IBM PC? (circle: Yes or No) Do you own an Apple computer? (circle: Yes or No)

24 Another option Add the necessary response categories and allow multiple responses. This is the preferable method because it provides more information than the previous method. What brand of computer do you own? (Check all that apply) __ Do not own a computer __ IBM PC __ Apple __ Other

25 Question 8 A good question leaves no ambiguity in the mind of the respondent. There should be only one correct or appropriate choice for the respondent to make. An obvious example is: Where did you grow up? __ A. country B. farm C. city

26 Any problem?? A person who grew up on a farm in the country would not know whether to select choice A or B. This question would not provide meaningful information. Worse than that, it could frustrate the respondent and the questionnaire might find its way to the trash.

27 Question 9 If a question does not produce variability in responses, it will not be possible to perform any statistical analyses on the item. For example: What do you think about this report? __ A. It's the worst report I've read B. It's somewhere between the worst and best C. It's the best report I've read

28 The problem is… Since almost all responses would be choice B, very little information is learned. Design your questions so they are sensitive to differences between respondents

29 Question 10 Among the most subtle mistakes in questionnaire design are questions that make an unwarranted assumption. An example of this type of mistake is: Are you satisfied with your current auto insurance? (Yes or No)

30 Here, the problem is…. This question will present a problem for someone who does not currently have auto insurance. This can easily be corrected by adding an additional response category. Are you satisfied with your current auto insurance? ___ Yes ___ No ___ Don't have auto insurance

31 Question 11 One of the most common mistaken assumptions is that the respondent knows the correct answer to the question. Industry surveys often contain very specific questions that the respondent may not know the answer to. For example: What percent of your budget do you spend on direct mail advertising? ____

32 The issue is…. Very few people would know the answer to this question without looking it up, and very few respondents will take the time and effort to look it up.

33 Question 12 Be careful not to lead the respondent into giving the answer we would like to receive. Leading questions are usually easily spotted because they use negative phraseology. As examples: Wouldn't you like to receive our free brochure? Don't you think the Congress is spending too much money?

34 Last, but not the least: Do you agree, disagree or have no opinion that this company has: A good vacation policy - agree/not sure/disagree. Good management feedback - agree/not sure/disagree. Good medical insurance - agree/not sure/disagree. High wages - agree/not sure/disagree.

35 A better layout would be: A good vacation policy AgreeNot SureDisagree Good management feedback Good medical insurance High wages

36 To Conclude The quality of your surveys depend on the time and effort taken to design them. The quality of your primary data depend on the quality of your surveys. The quality of your reports depend on the quality of your data. Good Luck!
