Answer Bank
a. intermediate precision
b. intra-assay precision
c. interlaboratory precision
d. instrument precision
e. precision

1. Precision is how close experimental values are to one another or also defined as the reproducibility of a result i.e. the ability to reproduce a measurement.

2. Instrument precision, also called Injection precision, is the reproducibility of an instrument reading when the same amount of one sample of what is being measures is introduced repeatedly into an instrument.

3. Intra-assay precision is the reproducibility of measurements on the same material several times by one person on one day with the same equipment.

4. Intermediate precision is also called Ruggedness and it refers to the reproducibility of measurements by different people, on different days, on different pieces of equipment within the same laboratory.

5. Interlaboratory precision is the reproducibility of a measurement from the same sample by different people in different laboratories
