We will generate a population 10,000 random numbers drawn from a Gaussian distribution with a mean of 50 and a standard deviation of 5.

It is a bad way to "detect" oultiers. Because median is mostly about how many numbers are on each side, an outlier wouldn't affect it any more then any other number.

Recently I have been trying to use ML to detect problems in machines like motors based on the vibration data collected from them. Nitin Panwar April 25, 2018 at 5: Running the example will first print the number of identified outliers and then the number of observations that are not outliers, demonstrating how to identify and filter out outliers respectively.

Let's consider a data set that represents the temperatures of 12 different objects in a room. If a data value is an outlier, but not a strong outlier, then we say that the value is a weak outlier.

Linked 0. Nevertheless, we can use statistical methods to identify observations that appear to be rare or unlikely given the available data.

## How to Use Statistics to Identify Outliers in Data

The maximum and minimum of a normally distributed sample is not normally distributed. Since 10 is not greater than 14, it is not a strong outlier. The pseudorandom number generator is seeded to ensure that we get the same sample of numbers each time the code is run.

This will be a time series data. As expected, the values are very close to the expected values. Isn't that a superior method? Alternately, the value in the record could be removed, and then imputed: So, before continuing, sort the values in your data set in this fashion. So the test should be based on the distribution of the extremes. Find the interquartile range.
