Answer:
Dot plot, because a small number of scores are reported individually.
Step-by-step explanation:
Histogram is usually used when a group of data to be represented is usually large and given in ranges or intervals.
However, for a data set, such as the scores of the group of 12 students who participated in a dance competition are reported individually, and not as ranges or intervals, a dot plot would best for representing this small number of scores.
See attachment below to see how we can easily represent the given scores of the students on a dot plot. Each dot represents a score value for each student.
