    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.
