I am writing a scientific paper and am unsure if I should be using "mean" or "mean of" each time I refer to a calculated mean number.
For example, should it be:
A) The samples had a mean of 54.1 reads B) The samples had a mean 54.1 reads
Or how about:
C) A mean of 54.1 reads were generated D) A mean 54.1 reads were generated
After reading through a few scientific articles it looks like both are used, but is one more correct or preferred? Does it change the meaning?
Thank you for your help.
