LEARNING GOALS
- B. CONCEPT ACQUISITION
- Challenges in validating the use of an instrument:
- a. When there is no objective gold standard (e.g. passage of time, what fluid to use in a thermometer)
- b. When direct observation is messy or impossible (e.g. radio waves, size)
- C. CONCEPT APPLICATION
- Explain how our ability to use the techniques for validating an instrument above can lead to more/less confidence in a given measurement.
- Identify where challenges in validating an instrument (and associated lack of confidence about what it is measuring) can make policy decisions more difficult.
