Hi there, I have a question about the difference of use piechart, dotplot, scatterplot, side by side barchart, boxplot , or histogram to represent the value, I have an example question here:

Suppose Professor Smith feels that more students in his class earned an A on the common test compared to Professor Yang's class.To prove his claim, he uses letter grades for the test scores.He finds that his class has 16 students who earned an A out of 35 students whereas in Professor Yang's class, only 5 out of 22 students earned an A.

What summary statistics and visual representation should Professor Smith use to display these findings?

Mean, standard deviation, and dotplot

Tally and pie chart

Correlation and scatterplot

two-way table and a side-by-side bar chart

Five number summary and boxplot
