WebAlthough you can have "many" outliers (in a large data set), it is impossible for "most" of the data points to be outside of the IQR. The IQR, or more specifically, the zone between Q1 and Q3, by definition contains the middle 50% of the data.

WebApr 5, 2024 · When using statistical indicators we typically define outliers in reference to the data we are using. We define a measurement for the “center” of the data and then determine how far away a point needs to be to be considered an outlier. There are two common statistical indicators that can be used: Distance from the mean in standard deviations
