• mean

• median

• mode

• range

Which term refers to how close a group of measurements are to each other?

• estimate

• percent error

• accuracy

• precision

If you add up the values in a data set and then divide the sum by the total number of values, the result will be the...

Scientists often rely on a(n) (a)   when they cannot obtain an exact number

When you (a)   measurements, the answer should only have the same number of significant figures as the measurement with the fewest significant figures.

A reliable measurement is both (a)   and precise.

Calculating percent error and checking the reasonableness of data are two of the math tools scientists use to analyze (a)   .

(a)   data are data that do not fit with the rest of a data set.

The significant figures in a measurement include all digits measured exactly, plus one (a)   digit.

A low percent error indicates that the result you obtained is

• accurate

• inaccurate

• an estimate

• anomalous data
