Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate for the data below. Water temperature in degree Celsius Choose the correct answer below. The order of measurement is most appropriate because the data can be ordered, but differences (obtained by subtraction) cannot be found or are meaningless. The ratio level of measurement is most appropriate because the data cannot be ordered. The ratio level of measurement is most appropriate because the data can be ordered differences (obtained by substractor) can be found and are meaningful, and there is a natural starting point. The interval level of measurement is most appropriate because the data can be ordered, difference can be found and are meaningful, and there is no natural starting zero point.
