1. A person is measuring the width of a board with a ruler, as shown. What could the person do to increase the accuracy and precision of the measurement? Be sure to
give an explanation of accuracy and precision

For the person you can improve the precision if you use a more accurate tape or ruler, that is, it has a smaller error or if you perform the measurement several times with the same ruler of the same value.

To improve accuracy, you can measure the width in various parts of the table and average so that this value is as close to the true value as possible.

Explanation:

For this exercise we must take the difference between precision and accuracy how much.

A measure is exact if its value is as expected

A measurement is accurate if the dispersion of the measured values is small

For the person you can improve the precision if you use a more accurate tape or ruler, that is, it has a smaller error or if you perform the measurement several times with the same ruler of the same value.

To improve accuracy, you can measure the width in various parts of the table and average so that this value is as close to the true value as possible.
