Which of the following would be most appropriate to display data if we want to show how frequently each number occurs? Is it option (A) line plot, (B) pie chart, (C) scatter plot, (D) Venn diagram, or (E) box plot?

A line plot shows us how frequently something occurs usually over a period of time. This suggests that option (A) could be the right answer. A pie chart is used to show parts or percentages of a whole. It does not give us the frequency or number of each item. A scatter plot is used to compare two sets of data and identify whether there is a correlation between them. A Venn diagram is also used to compare two or more data sets. Therefore, this is not the correct answer either. A box plot or box-and-whisker plot is used to show the range as well as the median and quartiles of a data set. It does not tell us the frequency of each item.

We can therefore conclude that the most appropriate way to display data if we want to show how frequently each number occurs is option (A) a line plot. We could also use bar graphs or pictographs to display this. However, they were not options in this question.
