In a scenario, we have 15 people in the team. We are requested to split into 3 groups(each has 5) to make the reporting.
By looking up a dictionary, the word "by" can mean:
used to show what unit of measurement or quantity is involved in selling, paying for, producing etc. something
For example, we are paid by the hour.
Similarly, can we use "by the group" to describe the idea above? Like:
We are requested to make the reporting by the group.
It doesn't seem right because "the group" sounds more like the specific group rather as a unit.
What would be the correct way(or the correct usage of by) to express it here, if it's not correct?
