PSYC 2101 Lecture Notes - Lecture 12: Likert Scale, Random Number Table, Cluster Sampling
Document Summary
Lecture 12/13: survey design: surveys are the most common form of psychological research. Participants may have different responses to each half: should senior citizens be given more money for recreation centers and food assistance programs, use neutral wording (not negative words). Interviews are better at: participation/completion, clarifying questions for respondents. Introducing bias: gaining responses to sensitive questions, cost, close-ended questions- researcher provides the response options. Everyone is comparable; works better when topic is well-defined: likert scale (1-7, yes/no, rating scales with anchors, strongly disagree strongly agree, not at all very much, semantic differentials, strong weak. Lecture 12/13: survey design: passive active, open-ended questions- ask questions, allow participant to respond freely. Provides picture of what people are really thinking. Works best at early stages of a project: probability sampling- people are selected randomly, simple random sampling- everyone has an equal chance of being selected for the sample.
