I want to know whether a noun after "distribution of" should be plural or singular. For example,
The distribution of height
The distribution of heights
It is possible that "height" is not a good example of countable noun. I am not interested in the specific example. To form a distribution, there should be multiple things, so intuitively, it should be plural to me. For the above example, I see many use "height" rather than "heights" and I want some explanation for that too. Please also consider below.
