Which of the following methods of sample data can help you present relative frequency distributions?

Stem-and leaf display

Bar Graph

Box Plot

All of the above

Solution

Relative frequency distributions require to display a ratio of frequency of a class interval to the total frequency. Hence, for every interval we compare the relativ frequency.

Such a comparison can be best presented through the form of a bar graph where the class intervals are represented on the x-axis and the y-axis consists of the relative frequency of each interval.

Answer: Bar Graph
