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

Organizing the data into a frequency distribution can make patterns within the data more evident.

What is the difference between relative frequency and cumulative frequency?

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 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 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.

Use the given minimum and maximum data entries, and the number of classes, to find the class width, the lower class limits, and the upper class limits. minimum = 8, maximum = 72, 6 classes The class width is _______ . Choose the correct lower class limits below.

Class width = 11 8, 19, 30, 41, 52, 63

Class width = 11 19, 29, 41, 52, 63, 73

Class width = 11 18, 29, 41, 51, 62, 73

Class width = 11 8, 18, 30, 40, 51, 63

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.

There is no difference between a frequency polygon and an ogive.

Use the given frequency distribution to find the midpoints.

41.5, 45.5, 49.5, 53.5, 57.5, 61.5, 65.5

42.5, 46.5, 50.5, 54.5, 58.5, 62.5, 66.5

40.5, 44.5, 48.5, 52.5, 56.5, 60.5, 64.5
