Quizplus · Accepted Answer

A bar graph is the best choice for showing the distribution of phones by manufacturer because it allows for easy comparison between the number of people who own each type of phone. A stemplot is not appropriate because it is used for displaying numerical data, not categorical data. A line graph is used to show trends over time, which is not relevant for this question. A histogram is used to show the distribution of numerical data, not categorical data. A phonograph is a device for playing back sound recordings and is not relevant to this question.
