Presentation 8-Questionnaire Design Flashcards
Case study
A detailed descriptive account of one individual, situation, organization, group, or other entity.
Survey
This is a term both used to designate a specific way of collecting data and to identify a broad research strategy. Survey data collection involves gathering information from individuals, called respondents by having them respond to questions.
Survey research
A broad research strategy that involves asking questions of a sample population, in a fairly short period of time, and testing
hypotheses or describing a situation based on their answers.
Reliability
This refers to a measure’s ability to yield consistent results each time it is applied.
Types of reliability
Internal reliability assesses the consistency of results across items within a test.
External reliability refers to the extent to which a measure varies from one use to another
Errors in measurement
Random Errors
These are neither consistent nor patterned eg. A respondent may misread or mismark an item on a questionnaire. They are essentially chance errors and can occur at any point of the research project.
SYSTEMATIC ERRORS
These are consistent and patterned. They cannot cancel themselves out. These are likely to lead to false conclusions. Eg. crime, delinquency.
Interview
A technique in which an interviewer reads questions to respondents and records their verbal responses.
Interviews offer the investigator a degree of flexibility not available with questionnaires.
One area of increased flexibility relates to the degree of structure built into an interview
Structured Interviews
This has the least structure. All the interviewer typically has for guidance is a general topic. By developing his or her own questions and probes as the interview progresses, the interviewer explores the topic with the respondent.
The approached is called un-standardised because each interviewer ask different questions and obtains different information from each respondent. There is a heavy reliance on the skills of the interviewer to ask good questions and to keep the interview going.
This can only be done if experienced interviewers are available. This unstructured approach makes unstandardized interviewing especially appropriate for exploratory research
Non- scheduled standardized
This adds more structure with the topic narrower and specific questions asked of the respondents.
However, the interview remains fairly conversational, the interviewer is free to probe, rephrase questions or take questions in whatever order best fits that particular interview.
The specific questions are of the open- ended type, allowing the respondents full freedom of expressions. Success with this type of interview requires an experienced interviewer.
Scheduled standardized.
Sometimes the schedule also contains acceptable rephrasing for questions and a selection of stock probes. Scheduled standardized interviews are fairly rigid and neither interviewer or respondent allowed to depart from the structure of the schedule.
Although some questions maybe open ended, most are closed ended. In fact, some scheduled standardized interviews are quite similar to a questionnaire except that the interviewer ask the questions rather than having the respondents read them
An interview schedule
contains specific instructions for the interviewer, specific questions in a fixed order, and transitions phases for the interviewer to use.
A questionnaire
is a set of written questions that people respond to directly on the form itself without the aid of an interviewer.
What does a questionnaire do
They are so designed that they can be answered without assistance. Of course, if a researcher hands a questionnaire to a respondent as we sometimes do, the respondent then has the opportunity to ask the researcher to clarify anything that is ambiguous.
A good questionnaire however should not require such assistance. In fact, researchers often mail questionnaires to respondents who thus have no opportunity to ask questions. The burden is therefore on the researchers to design questionnaires that
respondents can compete without assistance.
Structure and Design
One of the simplest and most important, tasks of questionnaire construction is the inclusion of precise directions for respondents.
If we want them to place an X in a box corresponding to the answer we will tell them precisely to do so. At each place in the questionnaire where the format changes, we include additional directions.
Order of questions
An element of questionnaire construction that takes careful consideration is the proper ordering of questions.
Careless ordering can lead to undesirable consequences, such as a reduced response rate or biased responses to questions. Generally, questions asked early in the questionnaire should not bias answers to those questions that come later.
Ordering of questions can also increase a respondent’s interest in answering a questionnaire, this is especially helpful for boosting response rates n mailed questionnaires.
