This time, I calculated a non-negative dataset which SD is larger than mean
I have seen many people use 'mean ± SD' to show mean and standard deviation.
But I wonder whether we can use that form for non-negative dataset.
The original data can't be lower than 0 but if I use ± it looks can be negative number(like 1 ± 3).
Is their no problem or should weI use other way?
