- Lesson 1, Part 3: Measurement and Scale
- "Measurement" Is:
- Measurement Scales
- A Real-Number System: Order, Distance, and Origin
- Scale and Real Number System: Example
- Movie Rating Scale
- Richter Magnitude Scale: -1.5-12
- What About Richter Earthquake Severity Scale?
- Richter Scale Presented by TNT Explosions
- 1976 Tangshan Earthquake 7.8; Deaths = 240,000!
- Measurement Scales and Computation
- Variable and Score Limits
- Real Score Limits

Variable and Score Limits

- Variable: Something which can vary in quantity or size
- Continuous: A variable which can, in theory, be measured to continuing finer degrees (e.g., scores on standing long jump test)
- Discrete: A variable which can assume values only at distinct or discrete points on a scale (e.g., number of runs scored in a baseball game)
- Score Limits: The number/score used to represent intervals
- [-----------] [----------] 9, 9, 9, 10, 10
- 9 10
