- Reliability is synonymous with consistency.
- A measurement that is unreliable is worthless.
- Would “1 + 1 = ” be a reliable question for basic math?
- What about for history?
- If your bathroom scale showed the same weight every time you stepped on it, it would be a reliable measure of weight.
- Imagine that every time you stepped on the scale it showed a different weight. Would you keep using this scale?
