What is the impact of the Margin of Error on the conclusions I can draw?
You should use the margin of error to consider how much more or less of ancestry from a population you may have. For example, if the percentage from a region is 50% and the margin of error is 2.5% then you might have as much as 52.5% of your genetic ancestry from that region or as little as 47.5%.
