The best representation of the data would be a D. Dot plot - because a small number of scores are reported individually and for each class.

While the two data visualization charts look good for plotting data frequencies, the choice goes to the data visualization chart that more accurately represents the small data set, which is the dot plot.

  • First, with a histogram, data ranges or intervals are involved unlike with a dot plot.  A dot plot represents each observation with a dot whereas a histogram divides the data into intervals, thus, hiding the identity of each observation.

  • Secondly, dot plots, as one of the simplest statistical plots, are more suitable for small to moderate-sized data sets. They highlight clusters, gaps, and outliers better than histograms.

  • Unfortunately, dot plots are not useful for large data sets because obtaining the data frequency is more difficult and time-consuming.
