    Sample Group is an automatic metadata flag assigned to each unique Visitor at random between 0 and 99.  The effect of this is that each Sample Group contains, roughly, 1% of your total Visitor population.  You can use this flag to establish Test and Train groups for experimentation and analysis within your product.

    Thank you Greg! 

    To get a better sense of what this means: for example I can create a segment of sample group 98, and this will guarantee that whatever I plan to test I will get to 1% of the total Visitor population. the more sample groups I add the more I control the increase of the % reach of the visitors?

    You've got it!  I will reiterate there is a roughness to that percentage due to how Visitors are randomly assigned and growing nature of Visitors to your product.  But the percentages will be ~1% per Sample Group.
