What are some benefits of representing data sets using frequency distributions?
Organizing the data into a frequency distribution makes it possible to graph quantitative data
It is easier to determine the minimum and maximum values of a data set when it has been arranged into a frequency distribution

What is the difference between relative frequency and cumulative frequency?
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.
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.
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.
There is no difference between the two.

What is the difference between a frequency polygon and an ogive?
A frequency polygon displays class frequencies while an ogive displays cumulative frequencies
A frequency polygon is a line graph while an ogive is a histogram
It is easier to find patterns in the data from a frequency polygon than an ogive.
