This document discusses two statistical approaches: 1) using robust statistics like the median and median absolute deviation instead of the mean and standard deviation to make analyses less sensitive to outliers, and 2) taking a Bayesian perspective to update probabilities as new data is observed. Robust statistics provide more stable estimates than normal statistics when sample sizes are small and outliers are present. From a Bayesian viewpoint, initial probabilities are updated based on new observations and evidence to arrive at posterior probabilities.
