Students in 7th grade took a standardized math test that they also had taken in 5th grade. the collected data showed that in two years the median increased by three points, and the mean increased by around two and a half points. in terms of the context, what can you infer?

The students have learned much in grade 7 as compared to grade 5. The increase in median and mean predicts the increase in the individual score of the students.

Given information:

The median of score of students in grade 7 is increased by 3 points as compared to those in grade 5.

The mean is also increased by 2.5 points.

Based on the given information, it can be concluded that the score of students has been increased in 7th grade. This is possibly because they have learned more and better. A better understanding of the exam can also be the reason for a good score.

Therefore, the increase in median and mean predicts the increase in the individual score of the students.
