Focus on most useful tests? #364

Follow-up to #361: currently teaches all min, mean, max and sd to interactively test the center function. I'm confused by this number of tests TBH, and esp. explanation:

the original mean was about 1.75, so the lower bound from zero is now about -1.75. The mean of the centered data is 0.

and max is not refered to. I trust that it's mathematically correct, but only sd seems logical to me, which fits well to the "go further" part of the explanation.

Shall we remove the min and max tests, or should we maybe update the explanation with a back-reference to the center implementation:

the original mean was about 1.75. Because we the mean from all data, it seems correct that the lower bound shifted from 0 to now about -1.75. And that the mean of the centered data is now 0.

You know my vote :)

In case anyone else is reading, I prefer mean and sd only - don't find much value in max and min here.
