What is the difference between relative frequency and cumulative frequency?

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 dass is the number of observations in that class.
C. Relative frequency of a class is the number of observations in that dass, while cumulative frequency of a dass is the sum of all the frequencies.
D. There is no difference between the two.

Answer :

Answer:

A

Step-by-step explanation:

The relative frequency is calculated by dividing the frequency of that class to the sum of frequencies. It can be represented as

[tex]Relative frequency=\frac{f}{sum(f)}[/tex]

Hence, the relative frequency of class is the percentage or proportion of data lies in that class.

The cumulative frequency of a class is computed by adding the frequency of the respective class to the frequencies of all previous classes. The cumulative frequency of first class will always be equal to the frequency of first class.

Hence, the cumulative frequency  for a class is the sum of frequency for that class and the frequencies of all previous classes.
