What is an outlier in a dataset?

Back

An outlier is a data point that is significantly different from the other data points in a dataset, often lying outside 1.5 times the interquartile range (IQR) from the quartiles.

Back

The interquartile range (IQR) is calculated by subtracting the lower quartile (Q1) from the upper quartile (Q3): IQR = Q3 - Q1.
