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 here.
| Density ( | |||
| Trial | Set 1 | Set 2 | Set 3 |
| a | 1.380 | 1.347 | 1.418 |
| b | 1.400 | 1.479 | 1.499 |
| c | 1.374 | 1.401 | 1.301 |
Rank the data sets in decreasing order of precision.
Rank from most to least precise. To rank items as equivalent, overlap them.
