Compare the advantages and disadvantages of using open-ended questions with using closed-ended questions in survey research. (3 points)
Advantages of open-ended questions:
- these kinds of questions make it more probable that the researchers will stumble upon some facet that they hadn’t originally thought of when conceiving the questionnaire
- it is very useful in pilot studies or other preliminary studies that may use smaller samples
- later on these open-ended questions can be refined into closed-ended questions, which would allow for easier date encoding
- useful when there is not too much info to encode
- useful when the subject matter is difficult to narrow into a set of 4 alternatives
- potential to be more satisfying answers providing an overarching sense of completeness
- Disdvantages of open ended questions:
- the nature of answers that are more elaborate and sprawling makes it difficult to code
- researchers may have to break a cardinal rule of deciding in advance what they are looking for in the answers
- some people may find the process more taxing and laborious and have a difficult time articulating their answers
- this may lead to lower participation/respondent rate
- Advantages of closed-ended questions
- they are easier to code and analyze than open-ended questions
- respondents don’t have to think too hard about the answers as all alternatives are presented on the page
- respondents do not need to craft articulate answers
- can be far less time consuming encouraging higher rate of participation as a result
- disadvantages of closed-ended questions:
- might be difficult to reduce subject matter to neatly phrased closed-ended questions, so certain subjects may not be able to be covered by such questions
- tends to suggest alternatives that the participants may never have considered so they tend to do the thinking for the participants in a non-productive way
- may be more difficult to navigate researcher bias in how the questions are worded and also in that there are a set number of answers
- more difficult to assess when a person has not understood the question as there is less information to go on
Discuss the advantages and disadvantages of using mailed-out questionnaire surveys and using telephone surveys. (3 points)
advantages of mailed-out survey
- inexpensive
- no chance that the researcher or interviewer will bias the findings
- reduced chance of role demands affecting results
- useful in cases of acquiring info about intimate, personal or embarrassing subjects
disadvantages of mailed-out survey
- the questions need to be very clear and easy to answer
- no control over what order the questions are answered in
- no ability to explain the questions if they are not understood
- no control as to who truly answers the questions - they may be handed off to the children instead of the adults
- there may be a skew in the types of people who respond: people more likely to respond to surveys may have a particular personality quality which would slant the research data and make it non-representative of the greater population
- low response rate
advantages of telephone survey
- ability to have a rapport with respondents
- instant answers, no need to wait for the answers to return in the mail
- efficient and faster way to get through the questions
- can monitor if the interviewers are doing what they are supposed to be doing
- economically viable
- interviewers may be able to use computers as they ask the questions, which could be useful for things like branching items
disadvantages of telephone survey
- more viable for short and easy to accomplish surveys
- interviewer may bias the participants answer - may influence them in one way or another
- many people don’t like being disturbed to answer a survey, especially at dinner time, when these surveys happen often
- not quite as anonymous, so people may be hesitant to share personal, intimate details with a stranger
- role demands may play a role since there is a rapport and subjects may want to appear helpful
- appropriate sampling is difficult since people on cell-phones can be anywhere
