Question

the table shows results of an experiment that was replicated. accepted value: 130 experiment 1 129 experiment 2 131 experiment 3 129 experiment 4 132 which best describes the data? they are neither precise nor reproducible. they are precise but not reproducible. they are accurate and reproducible. they are accurate but not reproducible.

Explanation:

Precision refers to how close the measured values are to each other. Here, the values 129, 131, 129, 132 are relatively close, indicating precision. Reproducibility means getting similar results in repeated experiments, which is the case here. Accuracy is how close the measured values are to the accepted value. The values 129 - 132 are close to the accepted value of 130, so the data is accurate.

Answer:

They are accurate and reproducible.
