Each student is asked eight questions and is scored on the number of correct answers. The teachers create a dot plot of the scores from 15 students from Class A and 14 students from Class B, as shown.

Another score is added to the plot for Class B to make the median of the two data sets equal.

Click on the dot plot to show
where this score could have been added.

The question is basically asking you to put a dot on top of one of the numbers in Class B where it belongs.
