WebThe standard deviation (SD) is a single number that summarizes the variability in a dataset. It represents the typical distance between each data point and the mean. Smaller values indicate that the data points cluster closer to the mean—the values in the dataset are relatively consistent. WebMay 26, 2024 · Idea #1 — Winsorization. As we said, an outlier is an exceptionally high or low value. Based on this simple definition, a first idea to detect outliers would be to simply cut down the top x highest and lowest points of the dataset.
