What is the mode of the score,

24

explanation: mode is the value that repeats most often. so, in this case, 24 repeats the most often.

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
