Accuracy reliability and precision

Write your age in THREE different ways
The accuracy of each measurement depends on the quality of the measuring apparatus and the skill of the scientists taking the measurement. If the apparatus is faulty, or the scientists make a mistake, the measurement may be inaccurate.
For the data to be reliable, the difference the measurements must be small. There is always some differences in any set of measurements, whatever is being measured. There may be small differences in the way the measuring apparatus is used.
In this set of data, each measurement should only be slightly different from the others. The results are repeatable, meaning that each time a measurement is taken it has almost the same value. We can say that this set of data is reliable.
