Precision
Precision has two similar but slightly different meanings.1. How small your increments are. 2. How close repeats of the same IV value are. See examples below for clarification.
See examples
Reliability
Reliability is a measure of how sure you are that if you, or somebody else, repeated your investigation that you would get the same results. A method is more reliable if it has been repeated more times (with similar results each time).
See examples
Apparatus
Precision describes how close repeated measurements are to each other, even if they are not close to the true value. High precision means your data are tightly grouped, showing little variation due to random error.
Improvements
Accuracy
Accuracy describes how close a measurement is to the true or accepted value. High accuracy means your results are correct in relation to a known standard, not just consistent with each other.
See examples
Improvements
Validity
Validity describes whether an experiment actually measures what it is intended to measure. A valid investigation has a fair test design, with all relevant variables controlled so that only the independent variable affects the results.
