Percentage of outliers excluded from statistical analysis from The influence of aspect ratio and stroke pattern on force generation of a bat-inspired membrane wing

Prior to statistical analysis the data of coefficients of lift and drag for down- and upstroke, respectively, versus velocity ratio for these four cases was grouped into 15 bins for the five different wings individually. In each bin, all data points with a force coefficient more than ± 1 standard deviation from the mean of the force coefficient in the respective bin were excluded from further analysis. The remaining data points per bin were averaged and subjected to an ANCOVA analysis.
