For example, I measure test scores for different groups of students. When I present the results, should I say:

Here are test scores with respect to different student groups.


Here are test scores differentiated by student groups.

In fact, neither seems natural to me. Is there any better way of saying this?

  • The best alternative might be of: Here are the test scores of different student groups.

The most natural phrasing for similar contexts would be...

Here are the test scores grouped by [student nationality, or whatever].

...but OP's categorisation system already includes the word "group", so to avoid sounding clumsy he should simply omit the word before "by"...

Here are the test scores by student group.

Note that "grouped" is always optional in such constructions, but it's usually better included.

Taking the pedantic line, grouped by may be more appropriate if individual student test results are presented in a list containing a separate section for each group, and plain by if the only values shown are totals/averages for each group.


What about "Here are the test scores for each student group" ?
