Accuracy is:

• how close the measurements are to each other (the grouping).

• how close the measurements are to the true value (correctness).

• both of these

• none of these

Which of these data numbers would not be in the range of precision? 765.1m, 724.3m, 760.6m, 766.2m, 759.9m

We use the SI system in science class because: (check all that apply)

• It is base 10 - easy to convert

• The range (very small to very measurements)

• It is universal and official
