More About This Test

Your AncestrybyDNA™ Results consists of a certificate depicting your ancestral data in two formats:

• A table report listing your ancestral percentages of the four founder groups (European, African, East Asian, and Indigenous American)

• A bar graph showing the confidence intervals for your percentage ratios. The concept of confidence intervals is explained further below.

Your certificate is accompanied by a manual, which discusses the interpretation of test results in greater detail.

Confidence Interval

Because the test is based on statistics, your percentage results are given as a “maximum likelihood estimate.” The percentages in your report shows your most likely ancestry mix, and the confidence interval, indicated by the brackets near the top of each colored bar in your bar graph, will show the range of other possibilities that are two times less likely than the percentage specified in your table data.
