Adjust skewness and sample size to see how Bluewater Basin's nitrate distribution changes — and when the mean diverges from the median.
Right skew pulls the tail toward high values — common in contamination data where most readings are low but rare events are extreme.
With small samples, the histogram looks ragged and the mean is unstable. Watch how it stabilises as n grows.
