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
