Question

Strategies to increase the precision of experiment

Answer 1

Precision represents how close different sample measurements you take are to one another, and accuracy represents how close those sample measurements are to the true measurement. For example, the U.S. Mint manufactures pennies to a standard of 2.5 grams. If you weigh a penny five times, the closeness of each of your five measurements to one another is how precise your measurements are, but the closeness of the measurements to 2.5 grams is how accurate your measurements are. You can increase your precision in the lab by paying close attention to detail, using equipment properly and increasing your sample size.
