Question

what is the difference between relative frequency and cumulative frequency? choose the correct answer below. a. 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. 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 number of observations in that class, while cumulative frequency of a class is the sum of all the frequencies. d. there is no difference between the two.

Explanation:

Relative frequency is the proportion of data in a class (calculated as frequency of the class divided by total frequency). Cumulative frequency of a class is the sum of frequencies of that class and all previous classes.

Answer:

B. Relative frequency of a class is the proportion of the data in that class, while cumulative frequency of a class is the sum of the frequencies of that class and all previous classes.
