    Study Notes

    Types of Measurement

    • Qualitative measurement: involves assigning a descriptive label or category to a phenomenon (e.g., happy, sad, tall, short)
    • Quantitative measurement: involves assigning a numerical value to a phenomenon (e.g., height in inches, weight in pounds)

    Scales of Measurement

    • Nominal scale: categorical labels with no inherent order or numerical value (e.g., male/female, Democrat/Republican)
    • Ordinal scale: categorical labels with a natural order or ranking (e.g., high/medium/low, first/second/third)
    • Interval scale: numerical values with equal intervals between units (e.g., temperature in Celsius, IQ scores)
    • Ratio scale: numerical values with a true zero point and equal intervals between units (e.g., height in inches, weight in pounds)

    Measurement Properties

    • Accuracy: how close a measurement is to the true value
    • Precision: how close repeated measurements are to each other
    • Reliability: how consistent a measurement is across different observers or instruments
    • Validity: how well a measurement reflects the concept it is intended to measure

    Measurement Errors

    • Systematic error: a consistent deviation from the true value (e.g., a faulty instrument)
    • Random error: an unpredictable deviation from the true value (e.g., human error)

    Measurement Tools

    • Instruments: devices or tools used to make measurements (e.g., rulers, thermometers, survey questions)
    • Observations: direct or indirect observations of a phenomenon (e.g., watching a behavior, reviewing a document)

    Measurement Applications

    • Scientific research: to test hypotheses and theories
    • Evaluation: to assess the effectiveness of a program or intervention
    • Quality control: to ensure consistency and quality in a product or process
    • Healthcare: to diagnose and monitor medical conditions
