Accuracy and Precision for Data Collection
Guided Notes
3 key concepts
- 1
Accuracy refers to how close a measured value is to the true value, while precision refers to how close a set of measurements are to each other.
- 2
A data set can be accurate but imprecise due to human error, or inaccurate but precise due to faulty calibration of an instrument.
- 3
When taking measurements, always estimate one digit beyond the scale that is reported on the measuring instrument; however, counting numbers and defined values have infinite precision.
