To graph the frequencies of one scale variable, the best choice is to use either a histogram or frequency polygon. These types of graphs allow for the display of the distribution of the variable by showing the frequency of each value or group of values on the horizontal axis and the number of observations or percentage of observations on the vertical axis. A scatterplot or line graph is used to display the relationship between two variables, while a Pareto chart and bar graph are best used to display categorical data.
