Frequency Distribution - Answer: A frequency distribution lists each category of data
and the number of occurrences for each category of data.


A frequency distribution lists the number of occurrences of each category of data.


Relative Frequency - Answer: The relative frequency is the proportion (or percent) of
observations within a category and is found using the formula


Relative frequency = frequency/sum of all frequencies.


A relative frequency distribution lists the proportion of occurrences of each category of
data.,


Relative Frequency Distribution - Answer: A relative frequency distribution lists each
category of data together with the relative frequency.


Bar Graph - Answer: A bar graph is constructed by labeling each category of data on
either the horizontal or vertical axis and the frequency or relative frequency of the
category on the other axis. Rectangles or equal width are drawn for each category. The
height of each rectangle represents the category's frequency or relative frequency.


Pareto Chart - Answer: A Pareto chart is a bar graph whose bars are drawn in
decreasing order of frequency or relative frequency.


Pie Chart - Answer: A pie chart is a circle divided into sectors. Each sector represents a
category of data. The area of each sector is proportional to the frequency of the
category.
