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

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

Answer 2

The data collected for the purpose of scientific investigations from the ocean should be precise and accurate. The most precise data will be yielded by the temperature readings with a range of 2 degree Celsius. The chances of error in this data will be minimum as compared to the other data whose range is higher. Hence, the set of data with the temperature will yield precise results.
