Make a bar graph using the given frequencies.
-The frequency distribution indicates the test averages of a group of 336 students.

Question

Quizplus · Accepted Answer

A bar graph is the most suitable choice for displaying frequency distributions of categorical data. In this case, the data is the test averages of 336 students, which is a continuous numerical variable. However, the question does not provide any intervals or categories to group the test averages. Therefore, we cannot create a histogram or a frequency polygon. We can only create a simple bar graph with test averages on the x-axis and their corresponding frequencies on the y-axis. Choice B is the only option that shows a bar graph. The other options either show a line graph or a pie chart, which are not appropriate for displaying frequency distributions of numerical data. The data given in the frequency distribution is continuous data, which means it can be presented using a histogram or a frequency polygon. However, the question specifically asks for a bar graph, which is not appropriate for continuous data. Therefore, the only option that is a bar graph is B, which shows the frequency distribution of discrete data (i.e. the number of students with each grade level).
