Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate for the data below. Length of the side of a square in cm Choose the correct answer below. ○ A. The interval level of measurement is most appropriate because the data can be ordered, differences (obtained by subtraction) can be found and are meaningful, and there is no natural starting point. B. The nominal level of measurement is most appropriate because the data cannot be ordered. C. The ordinal level of measurement is most appropriate because the data can be ordered, but differences (obtained by subtraction) cannot be found or are meaningless. D. The ratio level of measurement is most appropriate because the data can be ordered, differences (obtained by subtraction) can be found and are meaningful, and there is a natural starting zero point.

For the measurement 74.38 mm, find (a) the degree of precision, (b) the value that is equal to or less than therange of values, and (c) the value that is greater than the range of values.

Express these ratios in lowest fractional form. 4. 27mm:45mm

(a) Did you grow up using the U.S. or the metric system of measurement? (b) Describe two examples in your life when you had to convert between the two systems of I measurement.
