What is ATTITUDE?
• Example of Attitude towards Big Bazar: – Vijay loves shopping at Big Bazar. He believes it is clean, conveniently located and has the lowest prices. He intends to shop there every month for groceries • An Attitude is: • Persistent over a period of time (changing a strongly held attitude requires substantial pressure) • Plays very important role in influencing behavior • Marketers believe that attitude directly effect purchase decisions • People hold attitude virtually about everything and marketers study many of them
Measurement
• Assignment of numbers or symbols to characteristics of object acc to rules. • We Do not measure objects, measure characteristics. • Thus we do not measure consumers we measure their:
– Perception – Attitude – Preferences etc.
Measurement
“If you can’t measure it, you can’t manage it.”

Scaling An Extension of Measurement
• Involves creating a continuum upon which measured objects are to be located. Ex.
Attitude towards departmental Store Extremely Unfavorable (1) Extremely Favorable (100)
Process of placing respondents on a continuum with respect to their attitude.
Primary Scales of Measurement
• Nominal Scales • Ordinal Scales • Interval Scales • Ratio Scales
PRIMARY SCALES OF MEASUREMENT
• F – Figurative / Nominal Scale • O – Ordinal Scale • U – Unconstrained zero point / Interval Scale • R – Ratio Scale
