LEARNING GOALS
- B. CONCEPT ACQUISITION
- Signal-to-Noise Ratio: The relative strength of signal compared to the relative strength of noise in a given context. Obtaining meaningful information from the world requires distinguishing signal from noise. Therefore, human cognition (both scientific and otherwise) relies on techniques and tools to suppress noise and/or amplify signal (i.e., increase signal-to-noise ratio).

LEARNING GOALS
- C. CONCEPT APPLICATION
- Roughly compare measurement techniques in terms of their resultant signal-to-noise ratios.
- Describe examples of techniques and tools to suppress noise and/or amplify signal (i.e., increase signal-to-noise ratio).
CLASS ELEMENTS
- Discussion Questions
- Suppose you're at a party, and hoping to make a new friend. What are some 'signals' you might be looking for to help you find a good candidate? What forms of 'noise' are likely to be mistaken for those 'signals'?
