Measurement (Operationalizing variables) Constructing Questionnaire Items Types of Questions: -Open-ended -Respondents provide their own answers Example: What is your age? ____yrs Example What effects, if any, do you think this program has on children under age 12? (leave a lot of lines/blanks for them to write) Advatnages: -allows in-depth responses -allows for unforeseen types of answers -good in “pilot” studies (test out your questionnaire first) Disadvantages: -difficult to code and analyze -could misinterpret responses (if someone writes too fast, there can be errors in sentence) -Close-ended -Respondents select from list of choices -Choices are exhaustive and mutually exclusive Advantages: -much easier to process -with continuous variables, can do more powerful statistical analysis (interval, ratio) Disadvantage: -May miss other possible response or more complex attitudes Some Closed-ended formats -Likert-type items: -Respondents indicate their agreement with a particular statement
