Study Notes
Ratio Scale
- An ordered scale where the difference between measurements is significant.
- Contains a true zero point, allowing for meaningful comparisons.
- Example of a ratio: Weight can be zero, indicating no weight at all.
- Interval scales differ as they may not have a true zero (e.g., temperature can be below zero).
Business Objectives for Data Collection
- Marketing research analysts evaluate the impact of new advertisements.
- Pharmaceutical manufacturers assess the effectiveness of new drugs against existing ones.
- Operations managers monitor manufacturing processes for quality assurance.
- Auditors review financial transactions for compliance with accounting standards.
- Example: Measuring customer service times in fast food for operational efficiency.
- Traffic volume measurement can justify advertising strategies at busy intersections.
Observational Studies
- Conducted by market researchers to gather customer feedback.
- Involves asking customers about service satisfaction, quality of interaction, and overall experience.
- Essential for gaining insights that are not easily quantifiable through other methods.
