We compute the mean over the 140 FTM measurements denoted as $\bar{d}$ and its standard deviation. We compute the mean over the 140 FTM measurements denoted as $\bar{d}$ and its standard deviation.
Because $\bar{d}$ can be larger or smaller than the true distance we use the difference between $\bar{d}$ and the true distance as error metric. Because $\bar{d}$ can be larger or smaller than the true distance we use the difference between $\bar{d}$ and the true distance as error metric.
