In measurements, what does the term 'precision' refer to? (2022)

Step 1: Understand that precision is about how close multiple measurements are to each other.
Step 2: Think of precision as consistency; if you measure something several times and get similar results, those measurements are precise.
Step 3: Remember that precision does not mean the measurements are correct (accurate); they can be consistently wrong.
Step 4: For example, if you measure the length of a table three times and get 100 cm each time, your measurements are precise.
Step 5: If the actual length of the table is 110 cm, your measurements are not accurate, but they are still precise.

Precision – Precision refers to the consistency of repeated measurements, indicating how close the measurements are to each other.
