Chapter 8: Surveys Chapter Preview: survey researchers prefer probability samples, and are wary of self- selected, convenience samples that do not represent the entire population. Census -data collection that includes every member of a population of interest. Ethics in Survey Research Sometimes, rarely though, an investigator needs to keep identification info for a long time; in such cases, data cannot be anonymous. So, sometimes, we do not ensure anonymity. But, here, they can at least assure confidentiality. Confidentiality means nobody will be able to connect a given person with participation in a study. When using mundane questions, it might be more reasonable to play down the confidentiality and anonymity aspects because they may distract a participant from the real purpose of the study. If you make a big point of assuring confidentiality and anonymity, it may arouse suspicions in those you survey. Participants must know that they can terminate their responses at any time, without penalty. Sampling frame -subset of the population from which a sample is selected. Creating survey questions is the hardest part. The quality of your data will be high when: 1. your question type meets your needs 2. the way you word your questions does not distort responses 3. format of your instrument promotes people’s willingness to complete the task. Question Types Advantage of Open-ended questions : provide a rich body of info Disadvantage of Open-ended questions : harder to categorize/sort/summarize b/c responses can go in any direction Respondent might fail to say some elements of response that researcher wants Advantage of Close-ended questions : much easier to score and summarize Investigator can make sure the respondent answers questions critical to project Disadvantage of close-ended questions : info in questions not as rich as with open-ended questions Satisficing -selecting the first acceptable answer, even if it is not the best answer. It is the tendency to be satisfied with the first acceptable response to a question or task, even if it is not the best response. The idea here is that people do not want to work any harder than they have to; it is easier to select response that somebody else provides than to work to find your own. So, satisficing is a limitation of the much-preferred close-ended questions. Satisficing is likely to occur for three reasons: 1. high task difficulty 2. lower respondent ability

3. low respondent motivation Minimize the occurrence of satisficing by: 1. create survey questions that are easy to understand 2. when asking people to remember events, it may help to ask several related questions so info is more accessible. 3. ranking a group of items rather than rating them individually because here, the respondent MUST consider every last option. This, however, could lead them to identify a point on the scale and generally to respond with that value (giving a 3 on every question) on virtually every item. This way of responding is called
