How well a measure generally represents a concept that you are trying to study is called?
Chapter 3. Operationalizing
1. Why do you need an operational definition when you already have a perfectly good conceptual definition? Show
2. Why can't you skip the conceptual definition and use only an operational definition to define your concept? i.e. why is it also necessary to have a conceptual definition?
3. What is the difference between conceptual and operational definitions?
4. A professor is studying learning and academic performance and uses GPA as a measure of how much her students have learned. Discuss why (or why not) this is an adequate operational definition of learning.
5. What role should essential qualities play in operational definitions?
6. What is the difference between a numeral and a number?
7. What is the difference between a number and an ordinal?
8. In what way is ratio scaling "stronger" than interval or ordinal scaling?
9. How do you tell which level of scaling is appropriate for a particular situation? (What aspects of the situation do you consider? Why do these aspects matter?)
10. Under what conditions would you have to use a lower level of scaling than the one that matches the phenomenon you want to measure? Give an example.
11. What can you do with interval or ratio scaling that you can't do with nominal or ordinal scaling?
12. Under what conditions does "0" not mean "none"? What are the consequences of this?
13. If you have a ratio-scaled variable and want to compare two values, what kind of comparisons can you make?
14. If you have an ordinal-scaled variable and want to compare two values, what kind of comparisons can you make?
15. If you have an interval-scaled variable and want to compare two values, what kind of comparisons can you make?

What are the measures of a study?Study Measures
Measures are the items in a research study to which the participant responds. Research measures include survey questions, interview questions, or constructed situations. When constructing interviews and surveys, it is important that the questions directly relate to the research questions.
Which term refers to stating how you will measure the concepts in your study?Learning Objectives
Operationalization is the process by which researchers conducting quantitative research spell out precisely how a concept will be measured. It involves identifying the specific research procedures we will use to gather data about our concepts.
How is a concept measured?We can measure concepts through direct and indirect observations:. Direct Observation: We can measure someone's weight or height. ... . Indirect Observation: We can use a questionnaire in which respondents provide answers to our questions about gender, income, age, attitudes, and behaviors.. |
