Open-ended question

Question 2

Answer 2

Closed-ended question

Question 3

What are the relative advantages and disadvantages of using open ended and closed ended questions in the survey?

Answer 3

The open ended question permits respondents to answer more completely and to reveal the reasoning behind their answers. Makes it more likely that the questionnaire will discover something not anticipated buys designers. Open-ended questions are harder to code because the answers are near to form and require more effort from the respondent and are more difficult for less articulate response to answer. Open-ended questions are more useful for smaller and preliminary studies

Closed ended questions are easier to code and analyze, there are fewer off-the-wall responses. Respondents do not have to think as hard or be able to articulate to formulate their answers. The disadvantages of closed ended questions are that the issues being studied may be too complex to reduce to a small set of alternatives, or the respondent may not agree with any of them, resulting in simplistic answers. Can you put words into the mouths of respondents, suggesting alternatives that they might never come up with themselves. Errors can happen for instance misinterpreting the question or a clerical error coding the data. The standardize Asian of open ended questions make some more suitable for larger studies

Question 4

Answer 4

Social desirability

Question 5

The tendency to agree with the statement on the questionnaire, regardless of its content. Common with binary closed ended questions such as agree/disagree or true/false

Answer 5

Acquiescence

Question 6

Answer 6

Likert scale

Question 7

Answer 7

Be written language familiar to all respondents.
Be clear and specific. Define the terms and the context clearly. Make alternatives clear, exhaustive, and mutually exclusive in the case of closed ended questions.
Avoid any leading, loaded, or double-barreled questions, which would result in biases in responses
Be as concise as possible and present all conditional information prior to the key idea

Question 10

What are the advantages and disadvantages of mail surveys?

Answer 10

Advantages: low-cost, no interviewer bias, best for personal and sensitive topics where anonymity is preserved

Disadvantages: questions must be self-explanatory, little control over order of questions answered, response bias for example low response or return rate

Question 11

What are the advantages and disadvantages of the personal interview?

Answer 11

Advantages: interviewer can motivate interviewees, clarify questions, and monitor order of questions answered. Higher response or return rate than in mail surveys. Possible to use of visual aid

Disadvantages: interview were biased, much more expensive than Mail or telephone surveys, difficulty reaching interviewees, potential interviewer affect where respondents say what they think the interviewer wants to hear. Supervision of interviewers more difficult

Question 12

What are the advantages and disadvantages of the telephone survey?

Answer 12

Advantages: easier access to respondents, quick completion, tighter supervision of interviewers, low cost, and possibility of using computer-assisted interviews

Disadvantages: possible selection bias, only suitable for short straightforward surveys, possible interview were biased, telemarketing and donation solicitation and options to screen calls and to use voicemail have reduced excess ability. Impossible to use visual aids. Less anonymous than mail or web-based surveys

Question 13

What are the vantages and disadvantages of using Internet surveys?

Answer 13

Advantages: efficient, low cost and speedy, potential to reach a large number of respondents of diverse backgrounds and from difficult to access populations. Can control sequence and branching of questions, and can check for invalid response is easily and consistently

Disadvantages: response bias the same as other methods, selection bias for instance accessibility to the Internet, websites for special interest groups. Difficulty controlling how the surveys completed alone or in groups, clarity of instructions, limiting distractions. Difficulty and checking variables about the respondent such as their gender or age that are of interest to the researcher

Question 14

Answer 14

Haphazard sample

Question 15

Answer 15

Purpose of sample

Question 16

Answer 16

Convenience sample

Question 17

A sample in which every member of the population has an equal and independent chance of being selected

Answer 17

Random sample

Question 18

A population as it is defined for the purposes of selecting subjects for astudy. The population that you will work with for your particular study.

Answer 18

Sampling frame

Question 19

Individual member of a sampling frame

Answer 19

Element

Question 20

A probability sample that is not randomly selected

Answer 20

Systematic sample

Question 21

Group chosen from an entire population such that every member of the population has an equal and independent chance of being selected in a single sample

Answer 21

Simple random sample

Question 22

A random sample in which two or more subsamples are represented according to some predetermined portion, generally in the same proportion as they exist in the population

Answer 22

Stratified random sample

Question 23

Group selected by clusters or groupings from a larger population

Answer 23

Cluster sample. Used when the population would be impossible impractical to number, for instance making a list of every person in Canada would be impossible

Question 24

Distinguish between a sample, population, sampling frame, element

Answer 24

A sample of the subset of individuals, a population is all individuals of interest to the researcher, sampling frame is a specific list of individuals in the population, each individual who falls within the sampling frame is called an element

Question 25

The extent to which the results of a sample are generalizable to the population depends on the degree to which the sample is _________ of the population

Answer 25

Representative. A sample is representative of the population on the sample of the same distribution of characteristics as a population. When some segments of the population are overrepresented in the sample, selection bias results

Question 26

How can response rate be increased?

Answer 26

The highest response rate occurs for personal interview surveys. The response rate for mail surveys is highest when the questionnaire has a personal touch, the effort required from the respondent is minimal, the topic of the survey is of interest to the respondent, and the respondent identifies with the sponsoring organization or the researcher conducting the survey. Researchers can increase return rate by administering the survey in groups if attendance my group members is high

Question 27

Describe how questions should be ordered in a questionnaire

Answer 27

For self-administered questionnaires such as mail surveys, you should ask those questions first letter of greatest interest of the respondents so as to capture their attention, and to leave the questions about demographic data at the end.
