Question

Many kinds of data can be gathered in the study of ocean water. Predictions are based on accurate and precise scientific data. Which of these sets of data will yield the most precise data?
temperature readings that have a range of 2°C
depth readings that have a range of 4 km
salinity readings that have a range of 20%
density readings that have a range of 40 kg/L

Answer 1

Data are considered precise if repeated measurements yield similar values. If you have a large range of potential values, your data is not likely to be precise. From your options, I would say the first answer is the best one because the data ranges for the others are relatively bigger.
