Question

interpreting the data
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 around two and three points, and the mean increased by around two and a half points. in terms of the context, what can you infer?

Explanation:

The data (median and mean increase) from 5th to 7th grade math test shows that, on average (mean) and in the middle value (median) of scores, 7th graders performed better. This infers that over the two - year period (from 5th to 7th grade), the typical (median) and average (mean) math performance of these students improved. So we can infer that the 7th - grade students' math performance, on average and in terms of the middle score, has improved compared to their 5th - grade performance on this standardized test.

Answer:

The 7th - grade students' math performance (both the typical score as represented by the median and the average score as represented by the mean) has improved compared to their 5th - grade performance on this standardized math test.
