Notes.
The ratio between the sample medians, where the error bars were calculated from the corresponding 16th and 84th percentiles.
Results from a two-sided Welch’s t-test between the two sets of physical properties. The t-statistic tests whether the sample mean values are different, and the corresponding p-value gives the probability for the null hypothesis that the samples have identical mean values.
Results from a two-sided K-S test between the two sets of physical properties. The maximum distance between the two cumulative distribution functions is given by the K-S test statistic DKS, while the corresponding p-value describes the probability that the two data sets are drawn from the same underlying parent distribution.
