Expert Solution

Step 1

Accuracy and precision are essential properties of your measurements when relying on data to draw conclusions.

Each measurement in the series has a component of random error. This error causes them to vary to some extent even when measuring the same item.
Measurements are accurate when you measure the same item multiple times and the values are close together. However, accuracy does not say anything about whether the measured values are close to the correct value. Measurements can be close to each other but far from the correct value.

Thus, precision is how close the measurements are to each other.
