Many kinds of data can be gathered in the study of ocean water. predictions...
temperature readings that have a range of 2°C
The temperature has a range that is smaller compared to the other measures.
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.
