1. refers to how close a measurement is to the true or accepted value.
2. refers to how close repeated measurements are to each other.
3. A measuring instrument that consistently gives readings that are slightly higher than the actual value is experiencing a error.
1. A precise measurement is always an accurate measurement.
True
False
2. Random errors affect the precision of a measurement.
True
False
1. Which of the following scenarios best describes a situation with high precision but low accuracy?
A student measures the length of a table three times and gets 1.50 m, 1.51 m, and 1.49 m. The actual length is 1.50 m.
A dart player consistently hits the same spot on the dartboard, but it's far from the bullseye.
A scientist measures the mass of a sample five times and gets values that are all over the place, but average out to the true mass.
