arithmetic mean

(mathematics)
The mean of a list of N numbers calculated by dividing their sum by N. The arithmetic mean is appropriate for sets of numbers that are added together or that form an arithmetic series. If all the numbers in the list were changed to their arithmetic mean then their total would stay the same.

For sets of numbers that are multiplied together, the geometric mean is more appropriate.

The sigmoid shape still occurs since the lower bound for the truncation was set to zero, which is a lower value than the empirical mean. It also accounts for the large value of the Anderson-Darling statistic.

So much so, in fact, that quite a few philosophers call themselves "naturalists" while rejecting one or both of the doctrine's two most basic tenets, viz., that (i) the mind is amenable to study using the empirical means of the natural sciences, and (ii) explanatory accounts of mind need posit no supernatural or extraphysical things or properties.
