how close a measurement is to the accepted value

accuracy

how close a set of measurements are to eachother

precision

how do you determine the precision of a set of data?

calculate the range(highest-lowest)

how do you calculate the accuracy of a data point?

calculate percent error (error closest to zero is the most accurate)

What does negative percent error tell us about the data?

the experimental value was too large

What does a positive percent error tell us about the data?

the experimental value was too small
