An outlier is defined as being any point of data that lies over 1.5 IQRs below the first quartile (Q 1) or above the third quartile (Q 3)in a data set. High = (Q 3) + 1.5 IQR Low = (Q 1) – 1.5 IQR. Example Question: Find the outliers for the following data set: 3, 10, 14, 22, 19, 29, 70, 49, 36, 32.
