First calculate the mean per race, then use that to calculate the confidence interval. I feel it should be more representative of the actual typing performance, because some texts are really short and may have been typed several times.
Should investigate the mathematical theory behind this. I know there is a trick that can be done with variances, but I need to dig into it some more.
