## Accuracy and Precision
Accuracy and Precision are often used interchangeablly, but mean different things.

### Precision is about variability in repeat measurements
The precision of a measurement is the repeatibility of that measurement and expresses the variability within it. In other words, precision is being able to getting close to or the same measurments every time.
The precision of a measurement is the repeatibility of that measurement and expresses the variability within it. In other words, precision is being able to getting close to or the same measurements every time.
For example, if the ruler mentioned above that measured 1 meter as 0.8 meter, measured the distance as 0.80 m, 0.79 m, 0.80 m, 0.81 m and 0.80 m over successive mesurements the ruler would be quite precise (the measurements have low variability), whilst being inaccurate. Additionally, using the pi example as above, if your measurments constantly get 3.12, then they are precise, but not accurate.
