Which tool gives the most precise measurement?
which tool gives the most accurate measurement?
7.033, 6.91, 7.1
answer both.

When it comes to calculations and measurements, it is important to maintain precision and accuracy. Accuracy is the closeness of your measured data to the true or exact value. Precision is the closeness of all your measure data to each other. The end goal for every calculation is to have high precision and accuracy. In order to achieve this, as much as possible, you do not round off number not until you reach to the final answer. The more detailed the measurement is, the more precise and accurate. Therefore, among the given choices, the most precise is 7.033 because it measure up until the thousandths place.

Related to this topic, precision and accuracy is best met when you apply the rules of significant figures. These are the digits in your numbers that carry meaning. One of its rules state that all non-zero digits, the zeros between non-zero digits, zero's after the decimal point, are all significant. The significant figures also depend on the given data. In calculations, your final answer should contain the same number of significant digits of the least given data.
