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

Temperature readings with a range of 2°C will yield the most precise data.

Step-by-step explanation:

The most precise data would come from temperature readings that have a range of 2°C. The smaller the range, the more precise the data. For example, if the temperature readings have a range of 2°C, it means that the measurements will be very close to each other and provide a more accurate representation of the temperature.

On the other hand, depth readings that have a range of 4 km, salinity readings that have a range of 20%, and density readings that have a range of 40 kg/L will be less precise because they have larger ranges and the measurements will vary more.
