Data Management: Can someone please help?

This is just an exercise in data interpretation.

The teacher could think the test is too easy since the median was 98%. half of the kids scored 98% or more.

To justify the test to the principal, she would use the mean of 76%. You would expect that a C-grade would be an average.

The student that scored a 58% would tell their parents that the average was the mode, 45%, to make it sound like he scored more than the average, even though he still failed the test.

The main problem here, and the reason for the mode, median, and mean to be so different, is the small sample size.

Though, the median is really 95%, the data given to you is wrong.

The median is the amount where the same number of people got above it than below it. Since there is 13 people total, there is 6 above the one mark and 6 above it.
