Document Summary
Likert scale: rating scale, degree of agreement, multiple items w/terms) strongly agree/disagree, often 5 pt scale. Semantic differential format: rate target object using number scale w/ adjectives ex: rate food from 1-10. Double-barreled question: asks 2 questions in one - poor construct validity. Negatively worded questions: question is cognitively difficult, confusing, reduces construct validity. Response sets (non differentiation): type of shortcut respondents can take when answering survey questions. Acquiescence (yea-saying): when ppl say yes or strongly agree to every item, not thinking carefully. Fence sitting: playing it safe, answering in middle or idk especially when confusing/controversial topic. Desirable responding (faking good/faking bad): no truth,respondent worried, unpopular opinion,anonymous-help or hurt, no take it seriously. Researchers can"t assume the reasons people give for their own behavior are actual reasons, some can"t accurately explain their actions. Basis for frequency claims, also can be used to operationalize variables in association and causal claims, random sample very important.
