Boyd takes additional measurements of the mass of product formed in a reaction. He uses a balance that has smaller graduations than the first balance he used. What is Boyd most likely trying to change?
He is trying to increase his accuracy but not his precision.
He is trying to increase his precision but not his accuracy.
He is trying to decrease his precision and increase his accuracy.
He is trying to increase his precision and decrease his accuracy.

apparently not He is trying to increase his accuracy but not his precision.

The correct option is "He is trying to increase his accuracy but not his precision"

Explanation:

Accuracy of a measurement is when the value of the measurement is close to the actual value of that measurement while precision is when the experiment is repeated using the same instrument but obtaining different values.

When Boyd changed the weighing balance in his experiment to a smaller one, the smaller weighing balance has a better accuracy (smaller graduations) than the initially used one because the smaller weighing balance will provide a value close to the actual value of the mass of product. If he had however, repeated the experiment without changing the weighing balance, he would have sought to increase his precision.

From the description above, it can be said that Boyd was trying to increase his accuracy but not his precision

The answer is D) He is trying to increase his accuracy and precision.
