Modified Z-Score Explained (Python Outlier Detection)
Last time, we saw how Z-scores can actually hide outliers when extreme values distort the mean and standard deviation. In this video, I’ll show you the Modified Z-score, a robust method that uses the median and MAD to catch those hidden outliers.
We’ll code it in Python with Pandas, see why it works better, and apply a simple rule to flag extreme values.
👉 By the end, you’ll know exactly when to use Modified Z-score instead of regular Z-score.
