Final answer:
The answer is b) Precision. Repeating a scientific experiment multiple times improves the precision of the data.
Step-by-step explanation:
The answer to the question is b) Precision.
In a scientific experiment, repeating it multiple times helps to improve the precision of the data. Precision refers to the consistency or reproducibility of measurements. By repeating the experiment and obtaining similar results each time, scientists can increase the precision of their data.
For example, if a student measures the length of an object three times and gets measurements of 10.5 cm, 10.4 cm, and 10.6 cm, these measurements are precise because they are very close to each other. On the other hand, if the measurements were 10.5 cm, 11.3 cm, and 9.8 cm, they would not be considered precise.
