**Part B**. The accepted density of the sugar solution is 1.394 g/ mL . Based on the average value of each data set, rank the data sets in decreasing order of accuracy.

Rank from most to least accurate. To rank items as equivalent, overlap them.

a. Student 1

b. Student 2

c. Student 3

In a laboratory experiment, the density of a concentrated sugar solution was determined by measuring the volume of the solution and corresponding mass. Three students each made a set of measurements using a different balance and used the results to calculate density. Their results are summarized in the table and bar graph.

Accuracy describes the correlation between the measured value and the accepted value. The accuracy of a measurement, or set of measurements, can be expressed in terms of error:

The larger the error is, the less accurate the measurement.
