Essentially, precision and accuracy are the same thing; they have very alike denotations. However, for this question, the average deviation of the replicate data point is a measure of accuracy.
What is the difference?
The difference between precision and accuracy is very slim, considering they can be used as interchangeable terms for each other. The overlying separation of the definition of accuracy from precision is that accuracy deals more with a point’s exactness in comparison to an initial point. Precision on the contrary is a measure of how closely or far off data is distributed.
In this question, it is mentioned that replicate points (of the initial data points) are created after 5 experiments. Because the replications are being compared to the initial point, a measure of accuracy is being shown.
