7 important questions on Theoretical FW & Operational design Handout 1 (93 slides)
Measurement of variable Handout lesson 3
Why?
If unable to measure cannot test hypothesis and unanswered research questions
You also need next to object and characteristic of object: a Judge
often judge and object are same
Attribute (charac) - Object -Judge
Price consciousness - car buyers - car buyer
Self-esteem - dyslexic children - psychologist
Organizational commitment - school teachers - school teacher.
Marketing orientation - companies - researcher and or consultant
Product quality tablets - consumer - computer expert
Examples of multidimensional abstract concepts vs undimensional
Examples of multidimensional scales:
- service quality (dimensions: responsiveness, reliability, assurance, empathy, and tangibles)
- store loyalty (dimensions: cognitive, affective, and conative loyalty)
- power bases (dimensions: reward power, coercive power, legitimate power, referent power, and expert power)
Examples of unidimensionalscales:
- anger
- price perception
- endorser attractiveness
- buying intention
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
Operationalize service quality
- •Dimensions of service quality
- Reliability – ability to provide what was promised
- Assurance – knowledge and courtesy of employees and ability to convey trust
- Tangibles – physical facilities and appearance of personnel
- Empathy – degree of caring and individual attention
- Responsiveness – willingness to help customers and provide prompt service
Ad 2 Develop measurement scale
(There are existingmeasures of manyconcepts: Sources of existingmeasures are scientificjournalsand “scalehandbooks”, e.g. Marketing ScalesHandbookbyBruner, Henseland James (2005)
Ad 3 Response format definition - scale
- Nominal - categories by: (sorting) dept. , gender
- Ordinal - ordered categories - highest education completed
- Ratio - numbers with meaningful difference and a natural Zero (weighting scale starts with 0)
- Interval - numbers with meaningful difference (IQ score)
AD 4 Measurement scales
Ranking scales - comparison between objects, preferred choices and their ranking :
- paired comparison (2 objects to choose) , forced choice (rank objects relative to each other)
- Comparative scale (compared to point of reference)
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
