There Are Two Types Of Outliers
- Univariate outliers are extreme values that only relate to one variable. Sultan Kosen, who stands 8 feet, 2.8 inches (251 cm) tall, is the current tallest man in the world. This case is a rare univariate exception because it has one factor, height.
- Multivariate outliers are combinations of extreme or unusual values for at most two variables. If you look at the height and weight of an adult group, you may notice that one person is 5ft 9ins tall. This measurement would be within the normal range of this variable. This person might also be 110 lbs. This observation is within the normal range of the variable of interest, weight. These two observations are combined to create an adult who stands 5ft 9inches tall and is 110lbs. This is a remarkable combination. This is a multivariate outlier.
Outliers can be classified as any one of the following:
- Global outliers, also known as point outliers, are data points that lie far from the rest.
- Contextual outliers, also known as conditional or outliers, are values that significantly differ from the rest of data points in the same context. This means that a value that occurred in a different context may not be considered outlier. This category is often found in time series data.
- Collective outliers can be described as a subset or group of data points that is completely different from the whole dataset.
We now know what an outlier looks like, so let’s see how they end up in data sets.
How Can Outliers Get Into Datasets?
After we have learned what outliers look like and how to identify them it is worth asking how they end up in data sets in the first place.
Here are some common reasons for outliers in data:
- Human error when manually entering data, such a typo
- Intentional errors such as dummy-outliers in a dataset used to test detection methods
- Sampling errors are caused by the extraction or mixing of data from incorrect or multiple sources
- Data processing errors can result from data manipulation or unintended modifications to a dataset.
- Instrumental error can cause measurement errors
- Experiment planning and execution errors can result from data extraction or experiment planning.
- Natural outliers are those that occur naturally in the data, and not because of any error. These errors are called novelties.
How Do You Spot Outliers?
It is possible to spot outliers in small datasets. For example, if you have 28 26, 21, 24, and 78 data sets, you can see that the outlier is 78. However, when dealing with large datasets or big-data, additional tools are needed.
