Accepted Answer

Precision is the closeness of measurements to each other, while accuracy is the closeness of measurements to the true value. Percentile represents the percentage of data points below a certain value.

Precision refers to the consistency of repeated measurements, while accuracy refers to how close a measurement is to the true value.
For example, if a target is hit multiple times in the same spot, it is precise but may not be accurate if it is not hitting the bullseye.
Percentile is a way to represent the position of a particular value within a dataset in terms of percentage.
The 50th percentile represents the median, which is the middle value when the data is arranged in ascending order.
