the table shows results of an experiment that was replicated. 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. accepted value: 130 experiment 1 129 experiment 2 131 experiment 3 129 experiment 4 132
Answer
Explanation:
Step1: Define accuracy and precision
Accuracy is closeness to true - value. Precision is closeness of measurements to each other. Reproducibility means getting similar results on replication.
Step2: Check accuracy
The accepted value is 130. The values 129, 131, 129, 132 are close to 130, so the data is accurate.
Step3: Check precision
The values 129, 131, 129, 132 are relatively close to each other, so the data is precise.
Step4: Check reproducibility
Since the experiment was replicated and we got values close to each other, the data is reproducible.
Answer:
They are accurate and reproducible.
