Table 1.
Sample Characteristics.
Figure 1.
Distribution of mean error scores for actual raters (histogram blocks) and for simulated random raters (line).
The best possible error score is 0.36.
Figure 2.
Average Euclidean distance score by race/ethnicity.
Error bars show 95% CI of Mean.
Table 2.
Multiple regression with error score as the outcome variable, for each sample separately, and for both samples together.
Figure 3.
Averaged difference between observer and genetic estimates by self-identified race of observer.
Positive values indicate an overall overestimation of NA ancestry by the observers, compared to the genetic estimates. Error bars show 95% CI of Mean.
