2 Μαΐ 2019 · Dixon’s Q Test, often referred to simply as the Q Test, is a statistical test that is used for detecting outliers in a dataset. The test statistic for the Q test is as follows: Q = |xa – xb| / R. where xa is the suspected outlier, xb is the data point closest to xa, and R is the range of the dataset.
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.
Example. In the third exam/final exam example, you can determine if there is an outlier or not. If there is an outlier, as an exercise, delete it and fit the remaining data to a new line. For this example, the new line ought to fit the remaining data better.
