0.810g/mL-1.375g/mL-2.046g/mL are these numbers precise or accurate or both?
To determine if these numbers are precise, accurate, or both, we need to understand the difference between precision and accuracy:
- Precision refers to how closely individual measurements or results agree with each other. Precise measurements have very little variability or scatter.
- Accuracy, on the other hand, refers to how closely a measurement or result matches the true or accepted value. Accurate measurements have very little systematic or constant error.
Let's analyze each given number:
0.810 g/mL: Since we don't know the true or accepted value, we cannot determine accuracy. However, if we take multiple measurements of the same substance under the same conditions and obtain results close to each other, we can say it is precise.
1.375 g/mL: Again, without knowing the true or accepted value, we cannot determine accuracy. But if multiple measurements are close to each other, it shows precision.
2.046 g/mL: Similarly, we can only evaluate precision here without knowing the true or accepted value.
Therefore, based on the information provided, we can conclude that these numbers seem to be precise since they have consistent values. However, their accuracy cannot be determined unless compared to a true or accepted value for the substances being measured.
