⚠️ Outlier Test
Grubbs (iterative) · Dixon Q test
🔧 All Tools
Run an outlier test on one data set to spot anomalies. Grubbs uses Z and t critical values and removes one point at a time until none remain; Dixon Q is a quick check for the max/min value when n≤30. After finding an outlier, first verify the measurement / record is correct before deciding to remove it.
