Question

As a university instructor, charts are very useful to show statistical analysis of test scores to students. Students are always interested in how they scored compared to the whole class or where their score landed in the overall scheme of things. Which type of statistics would be most useful for comparisons? Which type of chart would be best to show the comparison of grades? How do charts help protect privacy of individual grades?

A histogram is built by speaking to the estimations or perceptions that are gathered on a level scale, the interim frequencies on a vertical scale, and drawing square shapes whose bases equivalent the class intervals and whose statures i.e., of heights are dictated by the relating class frequencies.
