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.
