Relative frequency of a class is the number of observations in that class, while cumulative frequency of a class is the sum of all the frequencies. B. Relative frequency of a class is the proportion of the data in that class, while cumulative frequency of a class is the number of observations in that class. C. Relative frequency of a class is the percentage of the data that falls in that class, while cumulative frequency of a class is the sum of the frequencies of that class and all previous classes. O D. There is no difference between the two.
Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate for the data below. Years in which U.S. presidents were inaugurated Choose the correct answer below. O A. The nominal level of measurement is most appropriate because the data cannot be ordered. OB. 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 point. OC. 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. OD. The interval level of measurement is most appropriate because the data can be ordered, differences can be found and are meaningful, and there is no natural starting zero point. DELL Nex
