Question

What data display type is best suited to show the distribution of exam scores?

Answer 1

A histogram is the best data display type to show the distribution of exam scores. This type of chart allows you to visualize the frequency of scores within specified ranges or intervals (bins), making it easy to see patterns such as the shape of the distribution, central tendency, and variability. Additionally, you can assess characteristics like skewness and the presence of any outliers in the score distribution. Other options could include a box plot (to show quartiles and medians) or a density plot, but for straightforward frequency analysis, a histogram is typically the most effective choice.
