Morphology
Winsorized + mean
While 'mean' clearly indicates an average, 'Winsorized' is an eponymous, technical adjective whose specific procedure (replacing extreme values before averaging) cannot be inferred from the name or the suffix '-ized' by an average B1 learner. The compound therefore only signals a modified mean but gives no predictable information about how it is modified, making it opaque without statistical knowledge.
Etymology
Winsorized mean is named for a practical trick to make averages safer from extreme numbers. To make a Winsorized mean, you replace the biggest and smallest values with the nearest remaining values so the mean is not pulled by 'outliers'.
