Answer
Accuracy refers to the closeness of a measured value to a standard or true value. Repeating the experiment multiple times does not directly imply accuracy unless the average approach is towards a proven standard.

Answer
Precision is all about the consistency of the measurements. By repeating the experiment and averaging results, we minimize the effect of random errors, leading to more consistent measurements, thus improving precision.

Answer
Validity denotes whether the experiment measures what it is supposed to measure. Simply repeating an experiment enhances data reliability but does not inherently affect the validity unless the experimental design is scrutinized.

Answer
Reliability refers to the consistency of a measure. By conducting the experiment three times and averaging the results, we reduce random errors and improve the reliability of the data, making it the most appropriate improvement.
