Twenty-five students took a math exam with 50 questions worth one point each. The data set shows the exam score of each student.
On the dot plot display, which category is over-represented?
Responses
A 20
B 30
C 40
D 50
D) 50
Since there are no scores of 0-10, 10-20, or 40-50 on the dot plot, the category of 50 is over-represented in the data set.
