Students in 5 different 2nd grade classes are timed to see how long it takes to correctly answer 50 addition and subtraction problems. Each class was then taught a different strategy for basic arithmetic for one month. After the month, the students were again timed to see how long it takes to correctly answer 50 similar problems. The dot plots below show the differences in times for the students (difference after before) for each of the five classes. Which dot plot appears to indicate an improvement in time for the class?
